Is Tsunami predictable? :biblio:
Bie was watching some videos on Youtube and suddenly it autoplayed a video of Tsunami hitting Japan in early 2010s. It still looks scary and sad. Bie got to thinking and wondering if Tsunami is predictable? Is it only be predictable after there is a huge earthquake? Is there any prediction about the next big Tsunami hitting anywhere?

No it can't be predicted. Although you can know where it's most likely to happen based on historical data.

Its impossible to predict before an earthquake, because the earthquake is what sets off the potential for the Tsunami. If there is no earthquake, there is no tsunami 
It is quite easy to predict them once an earthquake has hit, though. If the epicenter is in the water, and its over 7.5+, then, uhh, people should run.
In the 2004 Tsunami though, a lot of countries were unprepared in terms of infrastructure and alarms, which, I guess is why 250,000 people died.
There was a girl called Tilly Smith from Britain who was holidaying with her family in Thailand. She was 10. She had been studying tsunamis in school, and noticed that one of the warning signs was the water starting to "bubble". She told her parents and everyone got off the beach. She's credited with saving over 100 people's life and not a single person died on the beach.

I did some research and i understood that it can only be caused by a huge earthquake under an ocean. So this means it can only be predicted when there is an earthquake?
And if it is predictable like you said, why did it kill so many people in Japan which is a very modern country and I'm sure Japan was well aware of that huge earthquake?

wrong. what do you think we have a global tsunami warning system after the big tsunami in Thailand 2004 for?
tsunami can be predicted where it will hit as soon as an earthquake or any big geological impact, or in rare cases, human impact such as huge bomb explosion is detected.
in the matter of minutes, this can save many lives.

I think It can be predicted but only when there is a huge earthquake. That is why there were sometimes a Tsunami warning after a huge earthquake so people can find a safe place before the huge waves hit the coast in a couple hours.

In 2004 case, I think it killed a lot of people because it was during Christmas period when people went to the beach for vacation/holiday and the ability to save people from Tsunami in those countries were still weak compare to modern country like USA. Just look at Japan, Tsunami still killed a lot of people.

the tsunami was warned in Japan, people just didn't get to higher ground quick enough because the tsunami came too big too quickly.
if you talk about predicting an earthquake happening, it's a totally different topic. also, big earthquakes under the ocean don't always cause tsunami.
long story short:
- you can predict tsunami as soon as there's an earthquake or any other causes. it buys you few precious minutes to save as many lives as you can.
- you can't predict exactly when an earthquake will hit, therefore you can't predict exactly when a tsunami will come to evacuate everyone beforehand.

This!!
anyway, do you know or remember why Tsunami still took a lot of people's lives in Japan? I was surprised after I saw the number of death because Japan is like one of the most modern countries in the world.

Its because they happen so quickly. Like, its estimated that after the earthquake it was hitting some places up to 10 minutes after!
15,000-17,000 people died. Which is a hell of a lot, but it could probably still have been a lot worse given how destructive it was and the amount of people effected.
Its crazy watching the 2004 and 2011 tsunami though. It shows how destructive nature, and water, can be.

the tsunami in Japan 2011 was a sad event. the quake happened too close, just 72km offshore people literally had like a minute to run before the waves hit, that's why there's so many deaths
however, had it been any other country, it would've been a loooooooooooooootttttttttttt worse. Japanese people had been practicing for situations like this their whole life so they knew what to do not to mention the infrastructure is designed to handle earthquake so well, it saved millions of people

Only after 10 minutes? WOW
Anyway, I think the 2004 one was much more shocking because it hit many countries and a lot more people died but the 2011 one was huger right?

Only 72Km away? OMG that was so close. Tsunami's speed is around 800Km/hour so WOW they had like only a few minutes to run

You can predict Tsunami, but you can't predict earthquake, which is the cause of Tsunami
