Three minor earthquakes and a large aftershock have rattled parts of California in the 36 hours after a moderate, magnitude-5.1 quake hit an area outside Los Angeles Friday night, authorities said on Sunday.
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 U.S. Geologic Survey (USGS) said.
The seismic weekend began with a magnitude 5.1-earthquake at 8:18 p.m. Friday. The epicenter was placed 117 miles (about 187 kilometers) northeast of downtown Los Angeles, near the tiny Mojave Desert town of Ludlow.
That quake rocked nearby Barstow and the Apple Valley area, and was felt by some people in the L.A. basin.
On Sunday, a magnitude 3.0 aftershock struck the area at 1:07 p. m., rocking the same area jolted Friday.
Also on Sunday, a magnitude 3.5-earthquake apparently rocked the seafloor near Anacapa Island at 7:37 a.m., 66 miles (about 106kilometers) west of Los Angeles. More than four hours after the quake, a magnitude 3.1 temblor struck a geologically-active desert valley 170 miles (about 272 kilometers) northeast of the Los Angeles Civic Center.
At 8:07 a.m. Saturday, a magnitude 3.0 quake was measured with an epicenter 6 miles southeast of Olancha, a small town 140 miles (224 kilometers) north of Los Angeles. This quake was about 65 miles (104 kilometers) northwest of the Friday-night epicenter.
No injuries or damage were reported in any of the shakers.
Data about the smaller quakes have yet to be reviewed by scientists, and their sizes and epicenters have been calculated by USGS computers.
