A lot of that seismicity is related to geothermal activity...and there either is, or there are plans for, geothermal energy. So,...it's kind of like the geysers seismicity. the recent larger quake is south of Coso, though...close to but north of the Garlock fault. The Owens valley has big faults in it, and there was a almost M8 quake in 1872 or 1874 or so that killed 1/4(?) of population of Little Pine or Lone Pine or one of those Pines...luckily that added up to only a couple dozen...adobe houses killed. Most think that quake was right-lateral but there is a picture in a book showing a left-lateral offset...the assumption is that the picture was put in backwards (may have been Richter?). I've hear doubt expressed about this being right-lateral...Nicholas Pinter showed a picture at his thesis defense of a cinder cone cut and offset by a fault....pure normal slip...no strike-slip at all. I never followed up to see if the 1872 rupture ran this way...

You need to get more information from someone else...Don?
