Civic Center, at a depth of 8 km (or about 5 miles). This morning's quake is part of an on-going cluster of the past month.

The Yucca Valley area experienced a M3.7 quake this morning at 9:33 am. The epicenter was 5 miles southeast of Yucca Valley. Today's quake is an aftershock of the May 14 M4.9 Landers aftershock. It is likely to have been felt in Yucca Valley, although we do not have any reports as yet.
At 3:09 pm yesterday, there was a M2.8 quake in the Anza Borrego Desert, 11 miles southeast of Ocotillo Wells. Due to its remote epicentral location, it probably was not felt.
There was another small quake at 2:18 am today, this time located 6 miles north of Barstow. The magnitude was M2.7. This quake might or might not be considered a Landers aftershock; it occurred about 5 kilometers outside the aftershock zone.
There was just another possibly interesting quake: a M3.2, located 31 miles east of Shoshone. The location puts it just over the border in Nevada. The region is very sparsely populated, so we do not expect "felt" reports.
