Is there any way to see a map of quake activity for a certain time period? For example, is there a way to see a map of Southern California activity for between November 1, 2001 and present?

Also, I was wondering whether anyone knew whether present patterns throughout California were comparable to pre-Northridge or pre-Sylmar (1971) activity.

There have been some predictions for Southern California by some persons that have had apparently decent success. (Actually, there have been a lot of predictions for Southern California.)

I'm just looking for some additional information.
