What nincomepoop came up with the idiotic idea that California was going to slide into the Pacific?
That is sheerly idiotic.
In the next few million years a small part of the CA coast (including about half of San Francisco and the extreme western part of Marin county) with head up to the artic areas near Alaska, but the rest of CA isn't going anywhere.
Point the second. I'll take a major earthquake once every century over constant tornadoes and hurricanes any day. The east coast only gets flattened a few times a decade by hurricanes, and you guys get horrified by the thought of a few 4.0 tremblors that you can scarcely feel? Yeesh.
