Early Thursday morning, a swarm of earthquakes occurred near Aguanga and again Friday morning. On each day, the series of quakes began after 3 a.m.
On Thursday, the greatest-magnitude quakes were 2.9 and 3.0. The Friday quakes were similar, the largest magnitude was 3.1 and a 2.7 quake occurred later.
All were concentrated in the same area, about 4.5 to 5 miles northeast of Aguanga and 19.5 to 20 miles south/southeast of Valle Vista. It is about a mile south of Highway 371 and just west of the Cahuilla Indian Reservation.
Smaller quakes in this area continued into the weekend. Previously, on Saturday, Sept. 1, a 3.3 tremor was felt in the same area. And a two-day swarm occurred in the middle of August near this area.
No injuries or major damage have been reported.
