I guess this explains why, several years ago when my wife and I were in our RV on the coast road along the ocean in Oregon, we saw all the signs.
We were at least 300 feet above the ocean level and there were tsunami warning signs every mile along the highway.
Told my wife that if they were thinking that a tsunami was going to come up this high, the signs weren’t going to help.
Based on the waves and damage from previous earthquakes off of this coastline, at least a 6-8 meter tsunami is going to hit in the next 5-75 years. If not next year.
(Last Mag 8-9 earthquake there was 323 years ago. The usual interval is 350 years. )
An 8-10 meter tsunami is possible. Over 10 meter not very likely.
