Hello Russell,

I would describe a reactive quake as an extension of a larger strain pattern taking place along the plate boundary. The SAF has been a bit active to the north. At the linked map, you can see a small group of quakes just to the west of the Salton Sea. There are 5 of them now. These small quakes are all 5 Km or deeper, meaning they are in the basement complex of the Salton trough. This area "seems" to respond to higher seismicity levels in central California. I have seen the area react before. If I see enough of these, then I will do a full on analysis of it. Again, this is hypothetical at this point. But I must test it. Hope there is room on this forum for this kind of work. Critical comments always appreciated.
