As you may have noticed, the Recent Earthquake maps were not updating properly over the weekend. They seem to be okay now, but please remember that the supposed two-day "silence" was not real. We are in the process of reinserting the offending earthquakes.
Meanwhile, seismic activity has been fairly normal. The only quakes of any significance were: a M2.6 Hector aftershock at 1:09 am today, 34 miles south-southwest of Baker, and a M2.9 quake at 4:55 am today, 7 miles south-southeast of Lucerne Valley.
There were more quakes in northern Baja over the weekend. The largest ones were a M3.0 at 5:20 pm and a M3.6 at 5:21 pm, and a M3.0 at 11:51 pm, all on Friday, and a M3.3 at 6:44 am today. There were a number of smaller quakes, as well. The M3.6 was felt in El Centro.
We also got quite a few "felt" reports for something at around 3:30 pm on Friday, in the Palmdale area, and one more from the same area at about 9:00 am today. There were not any quakes recorded in that area at those times, so we assume that a sonic boom or similar air wave was felt.
