Why are there no actual videos of any hundreds of feet high tsunamis?

Question

Any tsunami video I look at barely looks like a 20 feet wave hitting shore. But wikipedia tells me there have been dozens of 100+ feet tsunamis even in the last 10 years.

Answer 1

There are videos like this: [Ice drop tsunami](https://m.youtube.com/watch?v=jX2mtToygPw)

And if I remember correctly, there’s a bay in Alaska where this happens semi regularly and sends waves 500 feet up the sides of the mountains across the bay.
