Three minor earthquakes and a large aftershock have rattled parts of California in the 36 hours after a moderate, magnitude 5.1 quake hit near Barstow Friday night.
A magnitude 3.0 aftershock struck the Barstow area at 1:07 p.m. Sunday, rocking the same area jolted Friday. No injuries or damage were reported in any of the shakers.
And there is no immediate indication that the quakes, which occurred hundreds of miles apart, are related. But some of them were felt in Los Angeles.
The seismic weekend began with a magnitude 5.1 earthquake at 8:18 p.m. Friday. The epicenter was placed 117 miles northeast of downtown Los Angeles, near the tiny Mojave Desert gas station hamlet of Ludlow.
That quake rocked nearby Barstow and the Apple Valley area, and was felt by some people in the L.A. basin.
At 8:07 a.m. Saturday, a magnitude 3.0 quake was measured with an epicenter 6 miles southeast of Olancha, a small town on U.S. 395 about 35 miles north of Inyokern and 140 miles north of Los Angeles. This quake was about 65 miles northwest of the Friday-night epicenter near Barstow.
At 7:37 a.m. Sunday, a magnitude 3.5 earthquake apparently rocked the seafloor near Anacapa Island, about 25 miles west of Malibu. The quake's epicenter was tentatively located 22 miles south-southwest of Port Hueneme, and 66 miles west of the Los Angeles Civic Center.
At 12:13 p.m. Sunday, a magnitude 3.1 earthquake struck in a geologically-active desert valley 15 miles north-northeast of Trona. The quake's epicenter was tentatively located 32 miles north-northeast of Ridgecrest, and 170 miles northeast of the Los Angeles Civic Center.
That quake was about 20 miles east of the Olancha temblor.
Less than an hour later, it was followed by the 3.0 Ludlow aftershock.
Automated seismographs indicate the main shock at Ludlow was followed by at least a dozen aftershocks that averaged about magnitude 1.5 before the 3.0 aftershock hit.
Data about the smaller quakes have yet to be reviewed by scientists, and their sizes and epicenters have been calculated by U.S. Geologic Survey computers.
