I think a number of people were surprised by the earthquakes in the Portland area recently. I remember someone commenting on “a new fault” that was found running through Portland. I don’t think people really realize how many faults there are, and those who have even taken an introductory Geology class may only think of the biggies, like the Juan De Fuca plate.
Well, there are lots of faults. This ought to help you sleep better.
It may not be directly related, but if there is a big earthquake, you may want to know about the Tsunami Innundation Line. Do you still want that coast cabin?
