The immense swell of a tsunami can grow up to 100 feet, hitting speeds over 500 mph -- a treacherous combination for anyone or anything in its path. Alex Gendler details the causes of these towering terrors and explains how scientists are seeking to reduce their destruction in the future.
Lesson by Alex Gendler, animation by Augenblick Studios.
"When nature is too powerful to stop, the safest course is to get out of its way"
a nice wisely quote... ^_^
What does that quotation mean?
Quotation is details from the text
Yo-Yo-
But what really makes tsunami is is the lava under the earthquake
I knew that because in a tsunami to move away from the wave deadly
To add to this:
- Wave lengths can be 100-1000km apart
- Waves can approach shore in 5 minutes intervals
- Time between each wave is 5-60 minutes
Please like this so others can see!
What happens when wave trough hits the ground first?
Hi, I do not think that there is any possible way to convert the energy of Tsunamis for something else as it could be too dagerous. The reason how we can get energy from lightning is that we can control where it strikes and then save the power. In this case we can not controll Tsunamis at all, and even if we did, we would not be able to see the eneregy in the water and catch up to its speed.
Yes but this would determine how powerful and fast the waves hit the coastline, right? Constructive and Destructive Waves vary.
Texturizer Also, There are also waves called Mega Tsunamis, which are caused by a large displacement of land in water, especially La Palma, a Canary Island with a super volcano that can create a landslide, causing waves 1 km /0.625 mi. /3300 feet high at first but then shrinking to 100 m/ 0.0625 mi./ 330 feet,

lol! It happened here in Cebu, Philippines (it's impossible for us to get hit by tsunamis as we are surrounded by nearby islands). It was Feb 2012. People ran for the mountains when one motorcyclist was looking for her daughter after an earthquake, "Chonamae, Chonamae!" But he pronounced it as "tsonami! tsonami!", creating a panic among the people and leaving their vehicles on the streets to run to the mountains. HAHAHA
(Disclaimer: It's just a legend. I don't know if it's true or not. But that's what people thought caused the panic.) 😂

Best explanation of what a tsunami is so far. Good job!
I watched this video for a school project about tsunamis thank you for the infomation
fun fact: the highest ever recorded tsunami was over 1100 metres in Alaska caused by a massive landslide, where only a father Fisherman and his son saw it. (but they survived)
i wish wouldve witnessed that let alone survive it
Akash Moana-Singh there were some bigger than that
Element 69 could u say which one plz
That one in Alaska was reported to be 550 metres high mate haha, there hasn't been waves around 1km since the meteor that whipped the dinosaurs out.
I thought the meteor caused water to evaporate

What this doesn't capture is the incredible wavelength of tsunamis. That's why most of the videos of the 2011 don't show towering waves bearing down on the shore. There, the leading edge of the tsunami usually wasn't very high, but the wave got gradually higher as more of the tsunami came ashore.
*Has two essays due tomorrow*
Brain: You need to find out how a tsunami works. Dew it.
I watched this when I was a kid, keep the good work up dude!
Damn. I remember the 2004 Tsunami. I was asleep when it happened, but I woke up and went to the balcony and I saw a huge flood. At first I thought it was heavy rain, but it was too much. An uncle said it must have been a tsunami.

*02:56** That is because the tsunami walls were 10 meters in height and the tsunami waves were 20 to 40.5 meters in height.*
*But despite that, it definitely slowed it a little, without these walls it would've been even worse.*
No, the highest tsunami wave from 2011 is 20 meters but the tsunami run-up reach as high as 40 meters.
Tsunami wave height is not the same as tsunami run-up height.
@@zeff8820 yes you are correct but most people don't know the correct terminology and simply refere to the run-up or on-shore height (40m in this case) when they say height not the Tsunami or off-shore height (20m).
Edit: typos
@@nalialightning6730 this is one of the example that shows the true height of the tsunami wave 2011, it's clearly the highest one is above 10 meters but i don't think it reached more than 20 meters and most of tsunami wave height footages from 2011 are around 8-10 meters.

"When nature is too powerful to stop the safest course is to get out of its way" .... where to???? I dont think the 18000 in Japan and the 200000 in Asia were just standing there enjoying the scene!!!
Jebus fuck, really? Did they really need to explain that you should get out of the way if you can, that sometimes you can't? Do you have people explain to you how to wipe your ass, and that sometimes you run out of toilet paper?
apburner1 If i can run then i will and not going to wait for someone to tell me ... I was talking about the people who could not... in their case, that safest way is inapplicable... sure they didnt need someone to tell them to run because they know that, but they could not due to the circumstances.
***** I like the idea of converting disasters to a power source, but yeah! sadly - as you said - we only use the power to kill each other
+Flarus 500mph could definately power entire villages in third world countries.I say let's do it! And while we are at it, could someone please create a way to capture and harvest lightning. All of that wasted energy going into the ground, I need that energy as my light bill gets quite high in the Arizona Summer.
I think the point is that with early warning, thanks to detection and monitoring systems, it may be possible to evacuate an area before the tsunami hits.
More than 1,500 people died last week in Sulawesi from a series of heavy earthquakes and a tsunami. The devastation has an aftermath of suffering due to loss of infrastructure, power, clean water, road access, food supplies, telecommunications, etc. Takes sometimes years to rebuild in developing countries.
Used this for my presentation, thanks
This was a really good video. It was really informative.
Hey! This is an irrelevant question but I am asking 'Which app are you using to animate this video??' Please answer as soon as possible.
And the video wad wonderful, thanks for giving such a nice video.
It doesn't look like a big wave really, you see the sea coming, and coming, and coming, and never retreat... this happens way faster than u think at the moment. Its like when you have a big water pool to swim, then the plastic tears and the water floods everything in the yard, now take that moment in your head with sea, a pool that has pretty much endless water and keeps flooding everything. Now that you have a picture of the flood, add fishing ships, big containers and cars floating moving towards you, when it reaches the town it will be with some planks part of trees or even walls from houses.
I'm not trying to argue here, its just the video shows like a rally big wave to surf in and fear, but its more like i said in the text before.
I'm from Chile, and the tsunami on 2010 killed more people than the earthquake itself.
Yup, kinda disappointed by how that misrepresented it in that way.
It's true, though massive waves like that are possible when the tsunami is caused by a landslide, look up the Lituya Bay tsunami.
Japan: oh I been in a tsunami
India:yes bro me to
Netherlands:what is a tsunami?
This was the first Ted Ed video I ever watched wayback 2014

Thx so much. Helped me with school project a lot
Thanks, I needed to do research of tsunamis for homework
Is it just me, or were other people gave this video and told to complete an assessment for school?
Very educational and easy to understand!
Ive just watched a tsunami video that occured in Ryoishi Town on 2011 and the tsunami didnt seem to be a giant wave. It was rather a fast and powerful watersurge that covered the whole harbor and everything else around the coastline in just a matter of a minute or less. A horrendous scene.
Remember. The camera guy always wins.
We used this exact video literally in our science class
This helped me ALOT THANK YOU😃
Thank you sm. I'll use it for my assessment
Thank you, this video explained it very clear for me, 😄
Just to clear something up, Fukushima didn't cause18000 deaths, the tsunami did. It is a little misleading in the video if you aren't listening carefully. Great video though. Thunderfoot has some good videos about the affect Fukushima had on people.
It's also important to note that the sea wall surrounding Fukushima wasn't as tall as it was supposed to be. Other nuclear plants' walls managed to stop the water due to being taller.
This is so important!
The tsunami was not the reason for the Fukushima nuclear disaster. The earthquake ruined the power plant.
@@HusseinDoha The tsunami was actually the reason. Fukushima took a direct hit from the waves and the reactor was flooded.

Great Video. Very well explained.
Thanks a lot, it helped me to learn about Tsunamis quite easily than reading thousands of text in books & explanation is nice.
this 3 minute video helped me more than my geography teacher did
Fun fact: You are only here for school work
Nah. I was just curious
In the year 1700, there was a massive earthquake in Alaska. It caused a tsunami over in Japan. Because there wasn’t any way of communicating soon enough back then, the people in Japan had no idea where this death wave came from.
Thank you for the lesson

@@Namrataa_Boraah oh hi army 💜
When I was young, my father taught me that. Now I see it visualized
The intro is so fascinating
It's good to have a lot of info.
You could plant massive concrete pillars in the coastal water so they cause the energy to diffuse and warp around them thus preventing the wave from forming as the energy changes path like a ball in a pachinko machine, loosing energy with each bounce but eh, do your own thing I guess.
+Meep “the” Changeling It would depend on how big the tsunami is. If you go and watch some of the footage of the tsunami in Japan in 2011, or the Southeast Asian Boxing Day tsunami, there was just so much energy that that really wouldn't have stopped it. It would have just pushed right past, and any debris that hit it might have pulled the pillars down anyway. You're also going to be hard pressed to put enough pillars up to make any difference even for a small tsunami along the entire seaboards of tsunami prone areas. It's cheaper and probably much more effective to monitor conditions and give evacuation warnings when it's thought a tsunami might be approaching. The only places something like that could be useful, and only if you built them big enough and strong enough, would be at places like the Fukushima reactor where, even with people evacuated, the surge of water could cause catastrophic consequences. Even then, higher seawalls would be better suited and probably more effective than the pillars. Also maybe not building nuclear reactors around the ocean or on fault lines, lol.
Wdym "Underwater Earthquakes", of course it was Poseidon.

thank you so much for this. this video was exactly the video i needed for my work. its absoulutely perfect
I need to write a paragraph so. I need to learn something
Nice
I may be wrong, but from what I remember, a tsunami isn't like a normal wave in that it is as if the sea level as a whole has risen - the wave stretches a great distance in depth.
You've reiterated the video. Congrats.
as is pointed out in the video.
It did mention a rise in sea level. Watch the video again.
It actually did mention it, if you watch it over again...
And also unlike wind waves tsunami transfers also water so im confused.
Great video. You explained very well. Keep up the good work from High Tunstall kids (7yG3).
The last sentence makes so much sense now
No, it was actually the Poseidon.
