I live on top of the San Andreas. Besides the usual 1.0 to 2.5s we have constantly, there has been lots of 2.5 to several 4.2s this past month. Some geologists say that this could mean the fault is just letting off tension and this will keep a big one from happening. Then there are the geologists who say it means pressure is building up. Such an inexact science, but so interesting when the ground isn't dropping out from under you.
