Coos Bay city hall has all of the cop cars parked under it, at street level. It was retrofitted to be more quaie-resistant, but I don’t see it being much of a factor if a big tsunami makes the streets impassable. Much of the town is built on fill, which would likely liquefy in a large quake. They tell us to keep gas tanks topped off. It might be a good source of gas for chainsaws, but folks aren’t going to do much driving.
I have a bug out bag in both of my vehicles and I wear quality hiking shoes in case I have to journey home after the quake/tsunami. Any gas I have access to at home will be for the 2200 watt generator.
A friend of mine was on the board of our local electric district. He found out some locations would be out of power for a year or more.
He moved East of the Cascades.
