What did they say? That fault fractures and the coast will drop about 10 feet?
Which fault? It’s kind of a mixed bag, here. North of Coos Bsy, we have sand dunes where the sea floor was thrust upwards. South of Coos Bsy. I know of a couple of big cedar stumps that are submerged except on the lowest tides. They “sank“ in the 1700 quake, I believe.
