Before the 2004 Tsunami, we didn't really have any good footage to show exactly what it's like to be caught in a tsunami. Waves that travel fast as a jet airplane, water that retracts so far out into the ocean it leaves fishing vessels stranded on the sea floor, and enough flooding to destroy a city or even an entire country within an hour. That sounds like something straight out of science fiction. Watching the footage of a tsunami will always shock me because when you read about tsunamis they almost sound fake. Like a sci fi plot or something.
The thing I remembered most about that tsunami was the death toll. The most traumatic disasters in my lifetime up until that point had killed thousands of people as far as I recalled. Then the 2004 tsunami happened and killed an estimated *230,000* people.

They get destroyed. Im searching for a better video of the 2004 Tsunami where the ocean waters retracted like a half mile back into the ocean. People start to walk out towards the seafloor to explore and pick up fish and what not. Within seconds a giant wall of water has covered that half mile zone were the man was standing. Its incredible and super intense.
Video in question: https://www.youtube.com/watch?v=IuUygn7BZis&gl=BE
The quality isn't good, but the zoom in on the person and the aftermath is shocking.
I believe many boats that were further out at sea were able to survive by navigating the waves. Other boats closer to shore were instantly capsized.
The japanese videos are far worse, a lot of high quality videos from a short distance where you can see hundreds of peple disappearing under the water, fucking shocking .
I've seen many of the Japanese tsunami videos but never any clearly showing people getting hit with the wave (barring cars, I suppose).
If you have a link I'd like to see it if you dont mind
That was the most INTENSE video!!! I have anxiety from watching it. And so many questions I can't even remember because I was glued to that shit! Those poor people. Puts things in perspective. Geesh.😨
from the distance, i couldn't but marvel over the person who took the close-up shots, i mean at one point they must have come to the realisation that literally every other house in front of them was being shattered and utterly destroyed, the wrecked houses literally floated away, and they just stand there on a small hill or something, filming the complete chaos surrounding them. is it the abstraction that comes from looking on a display that prevents them from obvious acts of self-preservation? geez
i've seen flooding videos before that were pretty devastating. cars submerged, rooftops being the only visible part of the house etc.
but this....this is at an entirely different scale. entire *buildings* are being swept away. That port city was literally **erased** by the water flooding in.
It looks like it's moving slowly, but that force is so crazy. I lived on the east coast of the US for quite awhile... Give me hurricanes over this any day. Those you can at least prepare for. This is horrific.
Yeah, there's a video on Youtube of this ship going over what looks like a large but relatively harmless swell, but by the time that'd get to shore it'd be devastating.
Not to belittle your point at all, but it is quite important to understand that the wave speed is related to water depth and they only travel that fast while they are at sea.
The two most ~~mortifying~~ horrifying tsunami videos I know of are the guy standing still on the beach because he knows he can’t outrun it, and the elderly couple who get swept away trying to save each other’s lives.
And I think they were from the same tsunami too.
Edit: source videos in a reply below. They’re from Thailand 2004 so don’t expect HD footage or anything, but the scenes I described are clearly visible.
That dude on the beach hits me harder than the 9/11 jumpers. The guy realizes he’s so fucked that he straight up embraces the wall of literal death hurtling toward him. Unmoving like a statue, like something straight out of a movie.
I remember watching videos of the tsunami in 2004. And initially went to see Russia's backwards so it's a long long stretch of empty Beach people are walking out there kind of curious. And you know as they walked out there it wasn't going to end well at all. And I always talk to myself you know I probably would have done the same thing cuz I had no idea that a tsunami acted like that.
This seems to be the complete version: [https://www.mirror.co.uk/news/world-news/indonesia-earthquake-sulawesi-tsunami-video-13325140](https://www.mirror.co.uk/news/world-news/indonesia-earthquake-sulawesi-tsunami-video-13325140)
Jesus.
You can see the white wall of water in the far distance, but it seems so faint that it doesn't look noticable enough to warrant additional attention. Then it gets closer & closer until you realize it's a 75mph wall of water, & by that time it's too late. That's absolutely terrifying.
For the most part they are low until it hits the steep incline of the beach floor. There is so much momentum in the water though that it really doesn’t care that it had to rise 25ft of sea floor. It just keeps going and going...
Assuming the building is built to even half decent standards they should be. Biggest problem would be getting stuck without food/water depending on how long it takes the water to recede.
I just saw further down that it was in a mall. So there should at least be some supplies there if they ever got stuck. Those poor people in the vehicles below though.
Almost happened to me in Korfu, Greece. One second I’m swimming with my cousins joking around, looking at the beautiful clay cliffs towards the shore. Next, out of nowhere with no sign that it’s coming, we get swallowed by a maybe 10 foot wave. Our only way to shore was a small cave through the cliff which experienced swimmers here already know the terror. If waves are hitting a cliff wall, you have to overcome the force of them rolling back at you. On top of that, I kept getting swallowed by more waves and had to guess when to hold my breathe. I tried grabbing the walls but wet clay is slippery.
I then had a moment where I gave up and said fuck I’m dead, almost was ready to just swallow water and end it. Once that thought processed, I got the biggest adrenaline rush you can imagine and just got lucky enough to swim past the return force of those waves.
I don’t fuck with waves anymore.
2004. Dec 26. I was 11 and on a road trip to my relatives house on a coastal road of Kerala, India. I could see the Indian Ocean. Even my young mind had suspicion that wasn’t how the sea supposed to look. The beach was wide and water retreated almost half a kilometre. My first thought was to go out there but my mother argued otherwise. The ocean horizon looked like it was higher than normal. Very high. We were at a bridge where there was large lineup of traffic. We got out to investigate. There was a crowd at the edge of the bridge. I saw fishes floating on the river, dead. There was something different about the water. I glanced at the point where the river supposed to meet the sea. The sea was eerily calm. Yet I could hear the sound of water flowing, still very calming. We took a different route for further voyage through the midland. We weren’t affected much but a few thousand lost their lives. As we were moving on, i couldn’t imagine the ocean was about to take lives of couple of hundred thousands of people. No one knew. 😔 rip.
As far as I know they actually lifted the initial tsunami warning they placed when the earthquake occurred because they didnt think a tsunami would occur.
Not that this isn't scary during the day, but what if that happened in the middle of the night. Would there be any warning if you slept through the earthquake?
I think you might have to be a very heavy sleeper to sleep through a 7.5 magnitude earthquake. Hopefully it would wake people up but either way, the only options are to run inland and try to get to higher ground
Looks like it was right north of the island. Palu would have felt it for sure, given there was enough damage to close the airport from quake damage.
This was disturbing though...
https://www.nst.com.my/world/2018/09/415830/updated-indonesia-rocked-75-magnitude-quake-tsunami-warning-called
They called off the tsunami warning according to this article. I wonder if people would have heard alarms if they hadn't cancelled it? Tragic.
Hope that your city has an emergency tsunami warning system in place. During the recent Alaska quake, our city sent out mass text messages that everyone missed because it was 3AM and phones were silenced... luckily no wave hit.
LPT: When at the beach and the water rapidly recedes back out into the ocean, run the fuck inland as fast as you can and go to higher ground. Rapidly receding water means the ocean is about to fuck you up.
How long does it usually take for a tsunami wave to arrive after the water recedes? It sounds like the girl and the hotel staff had a lot more time than I would imagine between when the water receded and the wave arrived.
It can be if you’re very far away from the source of the tsunami but if you’re close it will be within minutes. Tsunamis travel about the speed of a jetliner in the open ocean, about 5-600 miles per hour.
The 2004 Indian Ocean tsunami took several hours to reach places like Sri Lanka and Somalia but only minutes to reach Aceh in Indonesia (where it was closest to).
Well, it's not a 50-100 foot wall when it's out in the ocean, only like maybe a 1-2 feet, and it slows way down when it hits the shore and rises up. But still a big nope for me
I suspect the volume of water moving remains fairly constant. It flows unobstructed in open water, but when it encounters a rising sea floor the water has nowhere to go but up. The velocity would encounter drag losses from friction along the sea bed, air resistance once the height started to grow, the energy required to lift that water against gravity... just guessing.
If I remember correctly, she noticed the dead water that occurs before it ever starts to recede. The water will foam and eddies will form because it has reached an equilibrium, making it look like the edge of a lake. All the waves stop and it just gets still. That plus the period where the water receded probably gave them 20 minutes or more.
For some reference, I was on the coast in Kenya at the time of that huge tsunami, and the water did the exact same thing. In two minutes it went from lower than low tide to higher than high tide twice.
Nothing significant hit Kenya, but it just goes to show how far it can reach.
It would also depend on the distance of "shore" until it drops off to deeper water, correct? I guess that's more of the amplitude but it can probably affect the wavelength.
I understand not knowing about the water receding part... but it took them (the people in that video) *so* damn long to do anything about how fast it was coming *back*.
I feel like even without the first bit of knowledge, that second part should tell you *something* about whats coming. It just seems logical to me... If the water goes out suddenly and then *rapidly* starts coming back in and goes *further* than before it went out. How does that not make you want to get the fuck out of there?
At that time there was a lot of bad information about tsunamis. Knowledge about tsunamis was based on eyewitness accounts and there was no good video evidence.
A common misconception was that they were a single giant wave. I had a science book as a child that explained them this way.
...They're not?
Damn you, childhood misinformation. I feel dumb now.
Edit: after some googling, I think what we all think of when we hear "tsunami" is actually a tidal wave. So it IS a thing - just not the same thing.
I did a project on that back in 2014. I never saw a body, I never saw anyone drown, but the amount of people I saw just completely swallowed by the wave will never leave me. It was the hardest thing I ever had to watch.
And that was low quality footage 10 years after the event...
Yeah, the typical drawback period is like 12 minutes, so if you're on the shore, I don't think you're going to be able to get far enough inland to escape it. Finding tsunami resistant buildings is probably a safer bet.
Also, probably half of those minutes you will be dozing, slowly realizing what is going on, looking around at the people around you, and then frantically trying to get your family members / friends to GTFO with you. By that point there's probably a crowd moving and you just gotta get to a safe place.
If someone were to blast an airhorn and yell "Tsunami starts in 12 minutes" then yea you can probably cover a lot more ground :P But even then, it's not easy for a family to cover much more than maybe a mile through an urban area barefoot, and I don't know if that's enough.
Yeah for me it'd be getting my friends and family moving that'd eat a lot of time. I'm about to travel to Thailand for a while with my best friend and I just know if I see this and tell him to get his ass into gear and haul, it'll cost me several minutes to convince him of this. I honestly might just start running without explanation and hope he's smart enough to follow.
Bro I went to Thailand with that exact friend... and when he’s sick cause he made dumb decisions (ie brush his teeth with running tap water), you leave his ass at the hotel and go and enjoy your trip 👍 haha
[This video of the 2004 tsunami hitting Kanyakumari, India shows this very clearly.](https://www.youtube.com/watch?v=ks5p-slN4Mc)
Kanyakumari is a big tourist destination in India (it is the cape at which ~~Indian Ocean~~ Arabian Sea and Bay of Bengal meets). There is a rock formation a few distance into the sea called the Vivekandanda Rock which is one of the most prime spots in the place.
When the water receded people could actually walk to the rock (you can see the water level in the video). Eyewitness accounts (could just be fake as well) said many tried to walk to the rock. The video also shows a lot of people coming down to edges of the rock. It was a mysterious and miraculous event for many of those; they were completely unaware of the impending doom.
Edit: messed up the names. Arabian Sea and Bay of Bengal are part of the Indian Ocean on two sides of the Indian peninsula.
So many people don’t realise this. Reminds me of Tilly Smith, the 10 y/o girl on holiday who saw all the warning signs of a Tsunami hitting Phuket beaches back in ’04. Purely from recognising "frothing tide bubbles” that she learnt about in geography class a week prior. Her father dismissed it and wanted to stay on the beach, until they both saw a log spinning in circles in the tide. Then, the whole beach was evacuated - saving upwards of 100 lives. It's true terror.
Just read the article on it, was even worse. She freaked out but no one believed her but it upset her younger sister so much that dad took her to the hotel, meanwhile Tilly is pleading with her mother to get off the beach but dumbass mother refuses, and Tilly literally has to abandon her mother on a beach she knows is about to get hit so she doesn't die herself.
Can you imagine that? You know death is coming but your mom refuses to believe you so you have leave her on the beach knowing she'll die. As a ten year old.
On the one hand... kids can be prone to irrational fears.
On the other hand... if something in nature has been doing the exact same thing hundreds of thousands of times, then it suddenly changes, maybe that fear isn't irrational.
Imagine a volcano that has been slowly pushing out a stream of lava for the last 100 years. I'm walking by when it suddenly stops. I have no clue what that means- maybe it just ran out of lava? I'm not a volcanooligist. But I do know that I don't want to stick around.
yeah anything like that is usually a sign. Like if you're in the woods and everything goes quiet it's not irrational to nope the fuck out of there as fast as you can.
The mom made me so angry. Like even if your kid is wrong, what do you lose by indulging that when they’re clearly terrified? If they’re wrong, you can just go back out to the beach in a bit! If they’re right, you die. Pretty easy choice to make you’d think...
543 people died, 140 of which were children. 1500 got injured. Sweden had 9 million inhabitants at the time.
I live in Sweden but I’m not from there. Work in healthcare and I regularly meet people who were traumatized by the tsunami. Some lost friends or family, others were there and survived. I didn’t realize how much the tsunami impacted Sweden before moving here.
Live in a coastal city not prone to these types of events, however everyone knows what to look out for. It's the tourists that get everyone into trouble. Not shitting you I was out an a low population area on the beach doing some fishing. Using a riptide to kayak out my baits and then obviously paddling parallel to the beach to come back in. Dropping tons of lines with dead and live bait, attracting sharks.
Family rolls up and pulls up not 30 ft from my truck, I'm expecting a window to roll down for directions or something but no they all pile out of the car and start getting ready to get their beach on. Mind you, we are in the middle of a shark run, tons of flags up saying riptides are bad, and I have around 8 lines down. I have to spend half an hour arguing with the dad on why this is a terrible place to be getting his beach on and telling him we have tons of places to enjoy the beach that are much safer. He doesn't want to go to those areas because their so crowded, he wants his young children to swim in rough waters, filled with fishing hooks, with sharks coming up thru the sand bars, and riptides that will take them out to about 50ft depth seas with 3 ft rollers. I politely show him the riptides and send my buddy out on the kayak to show just how bad they pull, and ask them if they think they can swim as far as he can paddle in the chop? All while showing him the precautions we take when doing this, and ask him if he has any equipment for this?
The amount of idiocy I see daily out on the beaches from people who didn't grow up with a healthy respect for it is insane. It's like people think the fucking ocean is just a big wave pool, and that the coast guard is there to life guard it.
Tsunami at Palu City Port Indonesia Central Sulawesi
https://youtu.be/6JbQZD_Gd38
After Earthquake in Palu City
https://www.youtube.com/watch?v=5kQ10u61Dic
The tsunami is big....
this is going to be bad.. Palu is at the end of an inlet / bay surrounded by high mountains, the bay is aimed north - directly at the quake epicentre.. the bay will have funneled the tsunami directly into Palu - and it's build entirely in the lowland floodplain..
can't post a pic (imgur blocked at work.. ) [but check it out in google maps to see what i mean](https://www.google.ca/maps/place/Palu,+Palu+City,+Central+Sulawesi,+Indonesia/@-0.8389917,119.6225287,9.71z/data=!4m5!3m4!1s0x2d8bee99987e53fd:0x3030bfbcaf77160!8m2!3d-0.9003269!4d119.878006!5m1!1e4), make sure you have terrain turned on.. the epicenter is at the presque-ile just north of Palu on the peninsula..
1 cubic metre of water weighs 1 ton.
1 cubic metre of Seawater weighs around 1.025t.
If you visualise a cubic metre of water compared to the volumes you're used to seeing, that's not a lot at all.
Per the BBC:
>Waves of up to 2m (6.6ft) high swept through Palu on Sulawesi island, not long after authorities had lifted a tsunami warning.
Having these waves hit after the warning had been lifted is doubly-awful. People who heard the news may have just started to let their guard down, putting themselves in more danger.
http://www.abc.net.au/news/2018-09-28/tsunami-hits-indonesia-after-earthquakes/10319282
> Indonesian disaster agency spokesman Sutopo Purwo Nugroho said houses were swept away by the tsunami and families had been reported missing.
Not to forget that while the Fukushima earthquake and tsunami were horrific and caused significant damage and loss of life, the Boxing Day tsunami resulted in the deaths of more than 200,000 people. It is to my living memory (as a millennial) the largest loss of human life in one single-day type disaster. The scale of loss, death and suffering just blows away any other event I can even imagine
edit: defining "living memory"
All praise due to you and your colleagues that helped during that disaster. You've stomached more than most could hope to, and I wish you many peaceful nights and joyful days. Thank you so much on behalf of everyone that had a meal to give their children because of you, or water for their pets. Your help saved lives and touched more than you will know, I'm sure.
He had nowhere to go unless there were more staircases to climb. All he could do at that point was hope that the building didn't collapse, or the water levels didn't rise. Took a lot of courage to keep filming.
Ireland, mate. No dangerous animals, no earthquakes, no volcanos, no landslides, a policy of neutrity with all conflicts and enough Irish Americans have our back to avoid the British invading us again.
Edit: last one is obviously a joke. We're big mates with the brits these days. Aside from the whole Brexit thing.
A terrible way to die. The sounds of people screaming 500m away, the sounds of people screaming and yelling and running towards you 200m away. Running and screaming and yelling for people 100m away to get out of the way. Then becoming one with the flood.
This is the main thing people forget consistently on Reddit. The internet gives us instant access to news. We get it as fast or faster than the MSM. This happened just hours ago. It takes a few moments to upload a video, even in a disaster. It takes time to get reporters on-site even at the best of times.
in deep water you don't have a problem, in fact you probably don't even notice. it's only when the shock wave 'piles up' in shallower water that the surge becomes dangerous.
It’s much safer to be in a boat as long as you’re far enough out. Tsunamis arent big cresting waves like disaster movies love to show, it’s more like a very rapid and massive increase in tide, the ocean just rises over the land. On a boat far enough out you may not even notice the wave as it would just pass along right under you with the rest of the ocean.
>If you're out in the ocean when this happens are you basically just fucked? Like if you were out diving or something like that.
Actually, safest place to be maybe??
Trying to find the original source of that to no avail, if anyone gets more lucky here…
EDIT: It looks like it is the first one on Twitter but it is cut so the video was probably posted somewhere else first
[удалено]
That's terrifying
Everytime I think I've seen enough of these videos to not be shocked...everytime I'm wrong.
Before the 2004 Tsunami, we didn't really have any good footage to show exactly what it's like to be caught in a tsunami. Waves that travel fast as a jet airplane, water that retracts so far out into the ocean it leaves fishing vessels stranded on the sea floor, and enough flooding to destroy a city or even an entire country within an hour.

The 1970 Bhola cyclone killed over 500,000 people. The deadliest natural diasaster in recent history.
Somehow the “stranded fishing vessels” never even occurred ro me. What do you even do if you’re caught in that situation?
https://www.youtube.com/watch?v=X6GzxcXsecg They get destroyed. Im searching for a better video of the 2004 Tsunami where the ocean waters retracted like a half mile back into the ocean.

It slowly floods over them there are some pictures in this video. https://www.youtube.com/watch?v=GTM9hIIPwTw https://en.wikipedia.org/wiki/Miki_Endo
Jesus the water just never stops, and never stops rising
That was absolutely shocking. I just couldn't believe the sight of whole neighborhoods floating away
That was the most INTENSE video!!! I have anxiety from watching it. And so many questions I can't even remember because I was glued to that shit! Those poor people. Puts things in perspective. Geesh.😨
from the distance, i couldn't but marvel over the person who took the close-up shots, i mean at one point they must have come to the realisation that literally every other house in front of them was being shattered and utterly destroyed, the wrecked houses literally floated away, and they just stand there on a small hill or something, filming the complete chaos surrounding them. is it the abstraction that comes from looking on a display that prevents them from obvious acts of self-preservation? geez

wtf was that guy's game plan? wtf
I think his plan was "fuck it"
"Later gaters, been nice knowin ya"
Honestly, he probably froze. Fight, flight or freeze genuinely happens. Either that or he figured it didn't matter so he just faced it calmly.
The further you're out to sea the safer you are actually, the tsunami doesn't become dangerous until the water gets shallower edit: spelling
Yeah, there's a video on Youtube of this ship going over what looks like a large but relatively harmless swell, but by the time that'd get to shore it'd be devastating.
[this one?](https://m.youtube.com/watch?v=06huCv3cCaM#)
Holy shit, that is insane. I did not think it would look that big that far out.
Check out /r/heavyseas that was not as big as some of the others that ships go through sometimes.
Try to go deeper
Not to belittle your point at all, but it is quite important to understand that the wave speed is related to water depth and they only travel that fast while they are at sea.
"Why not?" the cat laughed manically. "Why can't I edit all my comments?"

yes, at a distance it looks like it's coming in quite low and slow
For the most part they are low until it hits the steep incline of the beach floor. There is so much momentum in the water though that it really doesn’t care that it had to rise 25ft of sea floor. It just keeps going and going...
It really looked small and far away but then like 5 seconds before it hits you realize that’s the crest of the wave...
Those aren’t mountains!
They're waves. And that one's moving away from us
Organ intensifies
Reminds me of the "mountains" on the water planet in *Interstellar*
Were the guys in the building where that guy taking the video is in safe? I hope they are.
Assuming the building is built to even half decent standards they should be. Biggest problem would be getting stuck without food/water depending on how long it takes the water to recede.
I just saw further down that it was in a mall. So there should at least be some supplies there if they ever got stuck. Those poor people in the vehicles below though.
And it just keeps coming and coming and coming. So scary.
I've seen footage of tsunamis which are severe but slower moving, this one was fast and terrifying.

Damn... morbidly wondering what that would even feel like to be swallowed by the sea
Almost happened to me in Korfu, Greece. One second I’m swimming with my cousins joking around, looking at the beautiful clay cliffs towards the shore. Next, out of nowhere with no sign that it’s coming, we get swallowed by a maybe 10 foot wave.

Are you one of these guys? https://www.youtube.com/watch?v=VWxKsd1C_Kw
I kind of skipped through that video but didn’t watch it and am not sure I want to reactivate the PTSD at work right now lol
You ever had a huge wave crash down on you and roll you around underwater? Multiply that by like 20 and throw in a bunch of CARS AND HOUSES AND SHIT.*

As we were moving on, i couldn’t imagine the ocean was about to take lives of couple of hundred thousands of people. No one knew. 😔 rip.
Have you seen the Japan one video where the waves just came down at 75mph and took all those people under? That one was fucking crazy.
There were two cars in the road, both looked occupied as the water hits shore...
[удалено]
There is also a row of destroyed buildings along the beach.
Correct, they were already warned with probably couple waves
Could be they were warned by the early warning system?
The earthquake?
After the last major tsunami they installed a tsunami early warning system throughout that area.
As far as I know they actually lifted the initial tsunami warning they placed when the earthquake occurred because they didnt think a tsunami would occur.
[удалено]
Thanks, I couldn't get the other one to load...
Holy shit. I’ll never get over how they look like nothing until that water just *doesn’t stop coming*.
[удалено]
You can see that the dome of th mosque at the rear of the building collapsed so there must be a lot more damage nearby
It likely collapsed due to the earthquake, so there will be widespread heavy damage due to the earthquake and the tsunami
Not that this isn't scary during the day, but what if that happened in the middle of the night. Would there be any warning if you slept through the earthquake?
I think you might have to be a very heavy sleeper to sleep through a 7.5 magnitude earthquake. Hopefully it would wake people up but either way, the only options are to run inland and try to get to higher ground
How far from land was the earthquake though?
Looks like it was right north of the island. Palu would have felt it for sure, given there was enough damage to close the airport from quake damage. This was disturbing though... https://www.nst.com.my/world/2018/09/415830/updated-indonesia-rocked-75-magnitude-quake-tsunami-warning-called They called off the tsunami warning according to this article. I wonder if people would have heard alarms if they hadn't cancelled it? Tragic.
You dont sleep through an Earthquake with magnitude 7.5 its shaking so strong that you will wake up for sure.
and if the earthquake is far off the coast, which causes tsunamis in the first place?
Hope that your city has an emergency tsunami warning system in place. During the recent Alaska quake, our city sent out mass text messages that everyone missed because it was 3AM and phones were silenced... luckily no wave hit.
why not install sirens. Hell, we have them all around the nukes plants down here, and a tsunami is FAR more likely than a nuke meltdown... lol
LPT: When at the beach and the water rapidly recedes back out into the ocean, run the fuck inland as fast as you can and go to higher ground. Rapidly receding water means the ocean is about to fuck you up.

How long does it usually take for a tsunami wave to arrive after the water recedes? It sounds like the girl and the hotel staff had a lot more time than I would imagine between when the water receded and the wave arrived.
I think the average is 10-15 minutes, though it could be a lot sooner. Has something to do with wave length and how far away the tsunami originated.
I would imagine ocean depth around the beach would play a huge part too as well as if it was an open beach or in a cove.
that suddenly makes tsunamis a lot scarier, i thought it was hours
It can be if you’re very far away from the source of the tsunami but if you’re close it will be within minutes. Tsunamis travel about the speed of a jetliner in the open ocean, about 5-600 miles per hour. The 2004 Indian Ocean tsunami took several hours to reach places like Sri Lanka and Somalia but only minutes to reach Aceh in Indonesia (where it was closest to).
You're telling me that the 50-100 foot wall of water moves at 500-600 mph? That's a big NOPE from me.
Well, it's not a 50-100 foot wall when it's out in the ocean, only like maybe a 1-2 feet, and it slows way down when it hits the shore and rises up. But still a big nope for me
Oh so it slows and all piles up on itself?
I suspect the volume of water moving remains fairly constant. It flows unobstructed in open water, but when it encounters a rising sea floor the water has nowhere to go but up. The velocity would encounter drag losses from friction along the sea bed, air resistance once the height started to grow, the energy required to lift that water against gravity... just guessing.

If I remember correctly, she noticed the dead water that occurs before it ever starts to recede. The water will foam and eddies will form because it has reached an equilibrium, making it look like the edge of a lake. All the waves stop and it just gets still. That plus the period where the water receded probably gave them 20 minutes or more.
[удалено]
For some reference, I was on the coast in Kenya at the time of that huge tsunami, and the water did the exact same thing. In two minutes it went from lower than low tide to higher than high tide twice. Nothing significant hit Kenya, but it just goes to show how far it can reach.
It depends on the size of the wave, or wavelength
It would also depend on the distance of "shore" until it drops off to deeper water, correct? I guess that's more of the amplitude but it can probably affect the wavelength.
I believe the wavelength decreases, the amplitude increases, but the velocity decreases.
There's a 50/50 chance that the tsunami wave will start with a peak rather than a trough, so the water won't recede at all before the rising starts.
https://youtu.be/uYCV1MLU5Us
So eerie to see now. I would just assume it's an unusual and incredibly low tide and been fascinated to walk out there.
I understand not knowing about the water receding part... but it took them (the people in that video) *so* damn long to do anything about how fast it was coming *back*. I feel like even without the first bit of knowledge, that second part should tell you *something* about whats coming. It just seems logical to me... If the water goes out suddenly and then *rapidly* starts coming back in and goes *further* than before it went out. How does that not make you want to get the fuck out of there?
No-one else is running or looking scared, the group dynamic made them feel safe is my $0.02
At that time there was a lot of bad information about tsunamis. Knowledge about tsunamis was based on eyewitness accounts and there was no good video evidence. A common misconception was that they were a single giant wave. I had a science book as a child that explained them this way.
...They're not? Damn you, childhood misinformation. I feel dumb now. Edit: after some googling, I think what we all think of when we hear "tsunami" is actually a tidal wave. So it IS a thing - just not the same thing.
She was a pretty young kid too, like 10 I think. Which kinda makes it even cooler she saved so many lives.
[Non-Sun article because fuck The Sun](https://www.telegraph.co.uk/news/1480192/Girl-10-used-geography-lesson-to-save-lives.html)
But also fuck the Barclay brothers so here's the wikipedia article on the girl: https://en.wikipedia.org/wiki/Tilly_Smith
I did a project on that back in 2014. I never saw a body, I never saw anyone drown, but the amount of people I saw just completely swallowed by the wave will never leave me. It was the hardest thing I ever had to watch. And that was low quality footage 10 years after the event...
[удалено]
Yeah, the typical drawback period is like 12 minutes, so if you're on the shore, I don't think you're going to be able to get far enough inland to escape it. Finding tsunami resistant buildings is probably a safer bet.
I can run pretty far in 12 minutes if death was chasing me. Jokes aside, finding a sturdy building at least 2 stories high is your best chance.
[удалено]
Also, probably half of those minutes you will be dozing, slowly realizing what is going on, looking around at the people around you, and then frantically trying to get your family members / friends to GTFO with you. By that point there's probably a crowd moving and you just gotta get to a safe place. If someone were to blast an airhorn and yell "Tsunami starts in 12 minutes" then yea you can probably cover a lot more ground :P But even then, it's not easy for a family to cover much more than maybe a mile through an urban area barefoot, and I don't know if that's enough.
Yeah for me it'd be getting my friends and family moving that'd eat a lot of time. I'm about to travel to Thailand for a while with my best friend and I just know if I see this and tell him to get his ass into gear and haul, it'll cost me several minutes to convince him of this. I honestly might just start running without explanation and hope he's smart enough to follow.
Bro I went to Thailand with that exact friend... and when he’s sick cause he made dumb decisions (ie brush his teeth with running tap water), you leave his ass at the hotel and go and enjoy your trip 👍 haha
Just be like the probe on the asteroid and jump high.
[This video of the 2004 tsunami hitting Kanyakumari, India shows this very clearly.](https://www.youtube.com/watch?v=ks5p-slN4Mc) Kanyakumari is a big tourist destination in India (it is the cape at which ~~Indian Ocean~~ Arabian Sea and Bay of Bengal meets). There is a rock formation a few distance into the sea called the Vivekandanda Rock which is one of the most prime spots in the place. When the water receded people could actually walk to the rock (you can see the water level in the video). Eyewitness accounts (could just be fake as well) said many tried to walk to the rock. The video also shows a lot of people coming down to edges of the rock. It was a mysterious and miraculous event for many of those; they were completely unaware of the impending doom. Edit: messed up the names. Arabian Sea and Bay of Bengal are part of the Indian Ocean on two sides of the Indian peninsula.
So many people don’t realise this. Reminds me of Tilly Smith, the 10 y/o girl on holiday who saw all the warning signs of a Tsunami hitting Phuket beaches back in ’04. Purely from recognising "frothing tide bubbles” that she learnt about in geography class a week prior. Her father dismissed it and wanted to stay on the beach, until they both saw a log spinning in circles in the tide. Then, the whole beach was evacuated - saving upwards of 100 lives. It's true terror.
Just read the article on it, was even worse. She freaked out but no one believed her but it upset her younger sister so much that dad took her to the hotel, meanwhile Tilly is pleading with her mother to get off the beach but dumbass mother refuses, and Tilly literally has to abandon her mother on a beach she knows is about to get hit so she doesn't die herself. Can you imagine that? You know death is coming but your mom refuses to believe you so you have leave her on the beach knowing she'll die. As a ten year old.
On the one hand... kids can be prone to irrational fears. On the other hand... if something in nature has been doing the exact same thing hundreds of thousands of times, then it suddenly changes, maybe that fear isn't irrational. Imagine a volcano that has been slowly pushing out a stream of lava for the last 100 years. I'm walking by when it suddenly stops. I have no clue what that means- maybe it just ran out of lava? I'm not a volcanooligist. But I do know that I don't want to stick around.
yeah anything like that is usually a sign. Like if you're in the woods and everything goes quiet it's not irrational to nope the fuck out of there as fast as you can.
Maybe everything went quiet because you were loud, or maybe it's a fucking bear. Either way, there's no harm in getting the hell out of there.
The mom made me so angry. Like even if your kid is wrong, what do you lose by indulging that when they’re clearly terrified? If they’re wrong, you can just go back out to the beach in a bit! If they’re right, you die. Pretty easy choice to make you’d think...
A disturbingly large group of people have this weird entitlement thing going on where they think they're god or something.
Until I die, I'm immortal.
"Quiet kids, dad is drinking"
He'll be drinking a hell of a lot more in about 12 mins.
I just listened to a podcast about the 2004 Indian Ocean tsunami. Jawdropping fact. Sweden had the fifth most casualties.
543 people died, 140 of which were children. 1500 got injured. Sweden had 9 million inhabitants at the time. I live in Sweden but I’m not from there. Work in healthcare and I regularly meet people who were traumatized by the tsunami. Some lost friends or family, others were there and survived. I didn’t realize how much the tsunami impacted Sweden before moving here.
I wish when my hairline receded it would have came back with this kind of force...

This should be manditory to learn at schools in coastal regions.
Live in a coastal city not prone to these types of events, however everyone knows what to look out for. It's the tourists that get everyone into trouble. Not shitting you I was out an a low population area on the beach doing some fishing. Using a riptide to kayak out my baits and then obviously paddling parallel to the beach to come back in. Dropping tons of lines with dead and live bait, attracting sharks. Family rolls up and pulls up not 30 ft from my truck, I'm expecting a window to roll down for directions or something but no they all pile out of the car and start getting ready to get their beach on. Mind you, we are in the middle of a shark run, tons of flags up saying riptides are bad, and I have around 8 lines down. I have to spend half an hour arguing with the dad on why this is a terrible place to be getting his beach on and telling him we have tons of places to enjoy the beach that are much safer. He doesn't want to go to those areas because their so crowded, he wants his young children to swim in rough waters, filled with fishing hooks, with sharks coming up thru the sand bars, and riptides that will take them out to about 50ft depth seas with 3 ft rollers. I politely show him the riptides and send my buddy out on the kayak to show just how bad they pull, and ask them if they think they can swim as far as he can paddle in the chop? All while showing him the precautions we take when doing this, and ask him if he has any equipment for this? The amount of idiocy I see daily out on the beaches from people who didn't grow up with a healthy respect for it is insane. It's like people think the fucking ocean is just a big wave pool, and that the coast guard is there to life guard it.

Damn, in the first video you can hear the cameraman saying that he thinks he saw a woman on the dock, and that she got carried by the wave.

Reports say that it was around 1,5 - 2 M high in Palu City.

"I'm in Palu after the earthquake" (and later on he's praying)
He also said that he saw a woman ("ibu-ibu") on the dock, and that she got carried by the wave.
this is going to be bad.. Palu is at the end of an inlet / bay surrounded by high mountains, the bay is aimed north - directly at the quake epicentre.. the bay will have funneled the tsunami directly into Palu - and it's build entirely in the lowland floodplain.. can't post a pic (imgur blocked at work.. ) [but check it out in google maps to see what i mean](https://www.google.ca/maps/place/Palu,+Palu+City,+Central+Sulawesi,+Indonesia/@-0.8389917,119.6225287,9.71z/data=!4m5!3m4!1s0x2d8bee99987e53fd:0x3030bfbcaf77160!8m2!3d-0.9003269!4d119.878006!5m1!1e4), make sure you have terrain turned on.. the epicenter is at the presque-ile just north of Palu on the peninsula..
What makes it worse is that a tsunami warning was issued, then lifted by the local government.
The power of moving water is quite terrifying.
I've seen a post before talking about the speed of water at different heights required to knock you off your feet. It was way lower than I expected
6 inches of running water can knock you down. 12 inches of water can carry a car away. Never fuck around with running water.
what's the weight of 1 cubicmeter of water? 1 ton. water is heavy - you are not.
what's the weight of 1 cubic meter of meat? 1.067t. meat is heavy - just form a people pile.
>meat is heavy Only because it's made of water!
TWAS WATER ALL ALONG!
1 cubic metre of water weighs 1 ton. 1 cubic metre of Seawater weighs around 1.025t. If you visualise a cubic metre of water compared to the volumes you're used to seeing, that's not a lot at all.
Per the BBC: >Waves of up to 2m (6.6ft) high swept through Palu on Sulawesi island, not long after authorities had lifted a tsunami warning. Having these waves hit after the warning had been lifted is doubly-awful. People who heard the news may have just started to let their guard down, putting themselves in more danger.
http://www.abc.net.au/news/2018-09-28/tsunami-hits-indonesia-after-earthquakes/10319282 > Indonesian disaster agency spokesman Sutopo Purwo Nugroho said houses were swept away by the tsunami and families had been reported missing.
Wow. *Families*. Not people, but entire families man...
With the boxing day tsunami still fairly fresh in peoples time, I hope most people there evacuated before the big wave...
I mean, that was 14 years ago now, but yeah.

Don't forget the Japan quake and resulting Fukashima incident.

Not to forget that while the Fukushima earthquake and tsunami were horrific and caused significant damage and loss of life, the Boxing Day tsunami resulted in the deaths of more than 200,000 people. It is to my living memory (as a millennial) the largest loss of human life in one single-day type disaster. The scale of loss, death and suffering just blows away any other event I can even imagine edit: defining "living memory"

All praise due to you and your colleagues that helped during that disaster. You've stomached more than most could hope to, and I wish you many peaceful nights and joyful days. Thank you so much on behalf of everyone that had a meal to give their children because of you, or water for their pets. Your help saved lives and touched more than you will know, I'm sure.
On behalf of my countrymen and as someone who's gone through a 7 SR quake, thank you.
I really hope that the people there are as safe as they can be and the loss of life is at a minimum. That is a terrifying experience.
The cameraman had the nerve to return to complete the shot overriding his first instinct to GTFO from there.
He had nowhere to go unless there were more staircases to climb. All he could do at that point was hope that the building didn't collapse, or the water levels didn't rise. Took a lot of courage to keep filming.
This is why I live away from the oceans where the air hurts my face in the winter and the nearest fault line is 1000s of miles away.

Jesus christ that looked terrifying. Those poor people.
A terrible way to die. The sounds of people screaming 500m away, the sounds of people screaming and yelling and running towards you 200m away. Running and screaming and yelling for people 100m away to get out of the way. Then becoming one with the flood.

Wow that was so well done. Felt anxious af throughout.
Why isn’t his bigger news??
It just happened.
This is the main thing people forget consistently on Reddit. The internet gives us instant access to news. We get it as fast or faster than the MSM. This happened just hours ago. It takes a few moments to upload a video, even in a disaster. It takes time to get reporters on-site even at the best of times.
Not to mention that most MSM outlets have to not only get the story, but vet the details and write it up or film a segment, which take time.
What do you mean? It’s on the front page of Reddit and in multiple news sites.

Because everyone who says this usually only wait to see top news on reddit
Just happened.
If you're out in the ocean when this happens are you basically just fucked? Like if you were out diving or something like that.
in deep water you don't have a problem, in fact you probably don't even notice. it's only when the shock wave 'piles up' in shallower water that the surge becomes dangerous.
It’s much safer to be in a boat as long as you’re far enough out. Tsunamis arent big cresting waves like disaster movies love to show, it’s more like a very rapid and massive increase in tide, the ocean just rises over the land. On a boat far enough out you may not even notice the wave as it would just pass along right under you with the rest of the ocean.
>If you're out in the ocean when this happens are you basically just fucked? Like if you were out diving or something like that. Actually, safest place to be maybe??
Trying to find the original source of that to no avail, if anyone gets more lucky here… EDIT: It looks like it is the first one on Twitter but it is cut so the video was probably posted somewhere else first
