Regional Activation throughout No. California, still waiting on Don's event though
Posted by Lowell on August 11, 2001 at 11:23:16:

Since the Ml 5.5 near Portola, there has been a substantial regional
activation of seismicity throughout the Central and northern California
region. Earthquakes included in this activation have been at Coso Junction (Ml 2.0),
Tres Pinos (Ml 2.0), Morgan Hill (Ml 2.0), Portola aftershocks (Ml 3.9), Cape Vizcaino (Ml 2.2),
Lake Pillsbury (Ml 2.1), Morro Bay (Ml 2.5) and perhaps Calistoga (Ml 1.4).
And, Don (and others), you might be interested in the progress of your
forecast for 8-12 August for the Central California area. Ther
following events were reported in the area today. They seem to
be zeroing in on your prediction. Good luck.


11AUG2001 12:45:08 36.7N 121.3W ML=2.0 NCSN S of Tres Pinos, CA (82 km)
11AUG2001 01:52:37 36.9N 121.5W ML=1.7 NCSN SSE of Gilroy, Ca (55 km)
11AUG2001 13:36:24 36.9N 121.5W ML=1.9 NCSN SSE of Gilroy, CA (55 km)
11AUG2001 11:51:37 36.9N 121.4W ML=1.3 NCSN N of Hollister, CA (62 km)
11AUG2001 12:10:50 37.3N 121.7W ML=2.0 NCSN N of Morgan Hill, CA (28 km)
11AUG2001 14:33:17 37.3N 122.1W ML=1.7 NCSN W of Cupertino, CA (14 km)

This represents a substantial increase in activity in this region
over the past two days and is obviously wide-spread suggesting
some kind of regional activation.
Still, while the Morgan Hill and Cupertino events match all other
aspects of your prediction, they are out of the magnitude range (Ml 2.8-4.2)
Don had predicted an event for 37.2N 122.0W. Still waiting for
something a bit larger?
