For the five years I have lived in the Bay Area, I have occasionally checked this map to see what recent earthquakes have happened round these parts. This is the least activity in a week I have seen. And there has been almost this little for some weeks now. The cluster of small quakes in the upper left corner is "The Geysers," an area of hydrothermal activity that always has many small quakes. On the San Andreas Fault and the Hayward Fault, the two main faults running through the Bay Area, there is not a single anything. No movement. This makes me very nervous. It makes me think that things have jammed. As long as there are many small earthquakes, my fabulously limited knowledge of seismography suggests that tension is being released. For the last several weeks there has been almost no release of tension on the faults around here. I consider it fairly likely we will have a significant earthquake pretty soon here. That said, I really don't know squat about earthquake prediction.
