Making Waves

[MisterVeritis]

A team modeling the aftermath of the asteroid impact that doomed the dinosaurs 66 million years ago say that the collision also created a global tsunami that devastated coastlines from North America to New Zealand.

...

The team modeled the tsunami propagation in two stages: the first model estimated the immediate waves from the impact event, and the second modeled how the tsunami emanated from the source on a global scale. Their work showed that, about 2.5 minutes after the asteroid impact, a wall of water 2.8 miles high was pushed outward from the source. (Compare that to the tallest wave ever recorded, a 1,719-foot wave caused by an earthquake in Alaska in 1958.)

Imagine a wave almost three miles high.

That sort of wave today would kill a large percentage of humans, as they tend to live close to the water.
