According to USGS




Aftershocks are earthquakes that follow the largest shock of an earthquake sequence. They are smaller than the mainshock and within 1-2 rupture lengths distance from the mainshock. Aftershocks can continue over a period of weeks, months, or years. In general, the larger the mainshock, the larger and more numerous the aftershocks, and the longer they will continue.


The key may be the "1-2 rupture lengths", see the map

Just had a small quake in central California and went to USGS and noticed I think that it was right on the fault line at 2.6km in depth is that bad on the line like that? Has anyone noticed a lot going on in that area by San Fran and North California lately or is it just me?earthquake.usgs.gov...

Pretty shallow !
But I'd say any small quake along there is OK, helps relieve the stress buildup.
Like the NZ scenario I'd say the San Andreas is a fault wher if there is NOTHING happening, thats the time to be concerned.

Hey Spacedman13, I just posted this map on the other thread, comparing it with the map from yesterday. It does visually look to be very alarming to me, so I hope some of the experts around here can help to figure this out.

This is from the last 30 minutes.
