Earthquake anon here, someone in a previous bread asked about two seismic events off the southern tip of San Clemente Island (Channel Islands). They look like deep water sea floor blasts… but the seismics are inconclusive.The oddity is that they were close together (15 minutes) 3.3 and 3.0m at about the same depth (8,000 ft). Because the military is very actively training in the area, it could easily be Navy. There is no drilling in the area. While the occurrence is at near the San Clemente fault, west of the fault in deeper water is not a major earthquakin' area. Most of the quakes top out at about 2m. The waveform is similar to an aircraft sonic boom… I'm actually not sure how that would be possible.
