Re: Well, i hope it happens ...
It'll likely wipe out the West Coast (and Baja) to boot. Well ... The West Coast up to the coastal range, anyway. No more Los Angeles, San Diego, San Francisco etc. No great loss. (I *think* I'm high enough to be out of direct harm's way ... The aftermath will be hell for survivors, though.)
When a similar thing happens in the Azores, the entire East Coast of the US will no longer exist. Again, no great loss (hopefully DC will be in session!). And again, the aftermath will be hell for survivors.
