Two interesting areas
#1
Two areas of note lately in California:

1. A lovely line of small quakes from the Ventura region NE to China Lake. Not unusual, but more quakes than I have seen there in a while. I would not be surprised for something on the White Wolf or other faults in that trend in the next 3 months.
2. East SF Bay area has been experiencing small quakes lately, and today had a 3.0 This area has been quiet for a long time, so wondering if something larger might be brewing in the next six months?

Don't want to clutter your trend, but sometimes I get an unscientific "hunch" about these things based upon increasing activity.

Was just a 3.5 near the White Wolf.

3.6 near San Ramon today (Aoril 2). If it had happened a week ago, I would have been there to feel it!

Another quake today (4/6). Looks as if this area is "waking up." (actually 3 quakes total this morning, 3.4, 3.6 and a 2 plus.)

Looks like there has been an increase along the more Southern Calaveras too. Think its in the area(Concord quakes) where stress was increased after the Napa quake. watching too from San Francisco.

4.0 today (July 21), so the area does seem to be waking up! Worth watching.

4.0 today (August 17). The area is definitely gearing up. Too bad that I will be in the area next week....wish I knew WHEN the bigger quake would happen?

I didn't feel the quake in SF though most people did. I was on ground level and walking when it happened.

Sharp drop in dilatometer at Garin site East of Hayward fault near Hayward/ Castro Valley.
See if any other instruments reflect changes tomorrow before making a prediction.
