For the most part the Pacific Plate and the North American Plate in the California region anyways is considered a transform Boundary, so a single earthquake most likely would not result in a trench or a rise of any significance.

I wouldn’t think it would be a single quake either—but several in rapid succession.

Then there’s the Hopi map here:

Thanks for your reply about the Wash Oregon thing.

Interesting.

Take your time.

Joe, how easy would it be to impose a State boundary lines map on top of this Hopi map???
