This is true and why tsunamis are scary af. Take this and try to imagine a taller tsunami https://youtu.be/8zoX9H6xiPo. It's actually hard because it doesn't even feel like a wave of some height. It feels like ocean rising.

Also "we are 300 years into a 250 year disaster cycle" is not a thing you want to read on a Monday. Though it looks like they got the cycle length just by dividing the total years by total number of previous earthquakes, so who knows if it's correct

That article scared me. The Cascadia Fault is a scary one. We are not (and arguably cannot really) prepared for an earthquake of that magnitude.
