Socal anon, today's Central California earthquake strikes me as unusual. First indication was it was broadcast on amber alert cell phone system but a larger quake two weeks ago was not despite being closer to large cities.
Second is the depth and clustering of initial quake and aftershocks. The location is Owens Valley which Los Angeles has sucked dry of water to divert to the city. There should be a pumping station nearby, will dig for location. The depth is quite shallow in an area I expect a deep sediment as the valley is between the Sierra Nevada and Panamint ranges. All of the earthquakes above 2.5m and almost all at any magnitude cluster within the lakebed which is now a salt or borax flat. Someone's DUMB disappear today? Seems like an ideal spot especially if that is a salt deposit.
