Since 1900 there have been at least 12 megatsunami with a height up to 1/2 a kilometre.
- taneq 3y agoWait, what? A tsunami 500m high is not something you’d miss.

- troupo 3y agoNote that this particular megatsunami is completely irrelevant when we're talking about Fukushima. Because context matters. You can't just say "oh we had 500 meter megatsunamis, Fukushima should have protected against those". The one you linked happened: - in a narrow bay - with a dual-slide that involved both a huge rockfall, and a huge release of sediment connected to a glacier breaking off --- It's also the first time I've heard of this event, and.... Just wow. Never thought it would be possible --- Edit: According to Wikipedia all megatsunamis recorded since 1900 were caused by landslides: https://en.m.wikipedia.org/wiki/Megatsunami https://en.m.wikipedia.org/wiki/Megatsunami Only some of the landslides were caused by earthquakes.
- verve_rat 3y agoThe point being, freak events are not nearly as freak as they are being made out to be. Edit: but I agree with the "wow". I can't even imagine what a wall of water that tall would look like. That is just so outside normal experience.
- troupo 3y ago> The point being, freak events are not nearly as freak as they are being made out to be. They are extremely rare. 12 megatsunamis in 123 years spread over the entire surface of the earth.
- taneq 3y agoOK so (a) this is a very different event to what we typically think of as a tsunami. And (b) holy crap that's terrifying.
