Also, side slip earthquakes dont tend to shake far away like a subduction quake.
If a large 8.0 or 9.0 subduction break were to happen, it would be felt 100s of miles away from the epicenter. The damage would be catastrophic.
We would most likely feel it very slightly here in NW AZ...depending on the geological mAkeup of the region between here and there.
Where you appear to be? Your gonna really experience something that will scare the heck out of you.
Some years ago I did a lot of digging into the Juan de Fuca earthquake situation, the one from 300 years ago dropped the coastline a bit, and since there were no “civilization” here, it didn’t have destruction that would happen now. Which, as you say, would be unimaginable. We’re on the east side of the Coast range, so no tsunami here. I figure we’d be totally on our own for a long, long time. Wood heat, well with large storage tank, generators, etc. I am not fond of earthquakes and if it holds off until I leave the planet I won’t mind. :😎
