Play disaster movie scenario here...
If there was a big one in Bay area, what are the realistic scenarios?
It looks to me as you fly in, that there is alot of flat plane on the south side of the bay that looks pretty marshy and unused. Is that likely to sink, or rise in a "Big One"?
Is the peninsula that San Fran is on vulnerable ... like literally falling into the sea?
IF there was a Big One, is that usually land coming UP or going DOWN?
