I never relized Puerto Rico had these concerns, but then up until say 2002 I never heard of Las Palmas in the Canary Islands either. Sounds like the East coast has alot to be concerned abourt.
Too bad New Madrid and San Andreas gets all the attention. The next big earthquake may not come from where everybodies looking, but it may come from where we're not looking.
What do you think where will it be, The big One????
