Another earthquake swarm has been rumbling along the California-Mexico border.
More than two dozen quakes greater than magnitude 2.5 have occurred since just after midnight Saturday, with epicenters about 175 miles southeast of downtown Los Angeles and 100 miles northeast of San Diego, according to the U.S. Geological Survey.
They have occurred largely along farmland between the towns of Brawley and Imperial in Imperial County. The largest quake was a magnitude 3.9 that struck at 4:05 p.m. Saturday, bringing light shaking to the Imperial Valley as well as south of the border and rattling Mexicali.

An even larger earthquake — a magnitude 4.1 — occurred at 5:17 a.m. Monday about 28 miles northwest of the swarm that began Saturday.
The epicenter of that quake was in a remote desert area east of Anza-Borrego Desert State Park, and weak shaking was felt as far away as San Diego, parts of Orange County, Temecula, the Coachella Valley, El Centro and Holtville.
