San Gregario Rocks
Posted by Petra on October 30, 2004 at 11:19:45:

Hi All,

It's been quite a morning. Not only did the San Gregario fault finally give something up, but we've also had 8 M class flares in the past 6 or so hours. (see link below). As you can see by this ANSS catalog search this location rarely has 3.0 quakes, with today's quake now becoming the second largest since 1898.

Could be an interesting day….Petra
