A wave almost 500 meters tall hit Alaska's Tracy Arm Fjord. This is the second-highest ever recorded, showing nature's power.

There was a megatsunami in Lituya Bay in 1958, https://en.m.wikipedia.org/wiki/1958_Lituya_Bay_earthquake_and_megatsunami . An earthquake caused a massive rockfall into a bay. The impact with the water generated a massive wave with a run up of 520m on the opposing slope. It was a shockingly powerful wave!

It turns out this kind of event is a risk in high latitude mountainous coastlines. The glaciers create steep valleys with fjords. The steep slopes have a high rockfall risk. In Norway, they are doing a mapping program to give warning before such disasters https://www.earthmagazine.org/article/comment-assessing-threat-massive-rock-slope-failures-norwegian-fjordlands

I think Frederik Pohl would be pleased that the crater named after him caused this.
