Please note this prediction for the eastbay. My reasons for the prediction are the latest quakes of magnitude 3. Note the second one today was not followed by any aftershocks compared with the pattern after yesterdays 3.

This region continues to experience swarms of quakes for the past 12 years. Danville and San Ramon have each been on epicenters of 4+ quakes during this time. Each of these swarms were proceeded by several 3s and micro quakes. The Lafayette/Orinda area is experiencing the same pattern. Two 3s and some micro quakes.
