Summary:
Lots of earthquakes recently and several more today. I'm disappointed that the recent M4.3 does not have a fault-plane solution. Judging from the weak ground motions, I think this is another one of those tension 'back-slip' earthquakes, responding to the main mechanism. Overall, the main mechanism responds to the high horizontal stress by contracting, and this allows the back-slip. TheContent analysis:
