- Hi,
- I am looking at the sfbay.gif file posted with the
- USGS weekly report for the week of January 15. I notice that
- ther is a cluster of six quakes with a magnitude 2.2 or
- greater at an apparently single spot near the San Andreas
- east of Watsonville (Hollister?). It has occurred to me that
- this spot has experienced a large number of small quakes over
- the past several weeks (based on these reports). Is there
- any explanation for this? Should people be concerned about
- the number of small quakes? I guess no one can make a
- prediction, and if you sit on the fault, a large number
- of small ones will be unsettling anyway, but i was just
- wondering if there is any research behind this type of
- string of quakes. (note also that this is miles south of
- the epicenter of Loma Prieta)...
