Looking at the USGS SoCal map, there is a lot of 3.x activity by Petrolia north of the bay area. There is a lot of little rattle on the San Andreas around Parkfield that takes a right into Nevada.

When there is a quake on the SW pacific plate rim there is usually an equivalent magnitude quake diagonally in the NE region, Alaska to Northern California somewhere.

Like I said earlier though, my casual observation is that heavy rains usually are associated with a sizeable quake in the northern half of the San Andreas somewhere in the bay area.

My guess is that it looks like two strikes for that region.

Good observations.

Please feel free to provide a link for a peer-reviewed correlated time series study showing that.
