Two small earthquakes within half an hour of each other shook Southern California Saturday evening, though no damage or injuries were reported.

According to the U.S. Geological Survey, the first earthquake at 6:50 p.m. local time, registered as a magnitude 3.0 on the Richter scale. The second earthquake, at 7:18 p.m., was a magnitude 4.2 at a depth of approximately five miles, though it had initially been recorded as a 4.5.

The USGS said that the epicenter for both earthquakes was near the town of Castaic, about 16 miles north of Santa Clarita and about 40 miles northwest of Los Angeles. Victoria Contreras, a clerk at a local market in Castaic, told the Los Angeles Times that the second earthquake's shaking lasted for approximately 45 seconds.

"All my bottles started rattling, then one great big boom," said Contreras. "I almost fell off the stool."

Despite the lack of injuries or damage, the temblor was widely felt across Los Angeles and Ventura counties. There were more than 1,500 postings on the USGS website from respondents saying they felt the quake.
