A day after a powerful quake rattled Southern California, residents across Los Angeles were shaken by a 7.1 temblor that rattled for up to 40 seconds, knocked out power and frayed already thin nerves.
The earthquake struck at 8:16 p.m. Friday as part of an earthquake swarm in the Searles Valley, according to the U.S. Geological Survey. The earthquake struck nearly 9 miles west-southwest of Searles Valley.
“Every earthquake makes another earthquake more likely,” said seismologist Lucy Jones. “Yesterday’s 6.4 is now a foreshock, and that 7.1 aftershock has become the main shock.”
The quake happened in the same location where a 6.4 quake happened Thursday, according to the U.S. Geological Survey.
Officials scrambled to assess the damage.
The LA Department of Water and Power reported outage possibly due to the earthquake in the Encino/Valley Glen area, affecting about 1,000 customers.
LAX officials worked to clear the runways and inspect them, officials said. The Los Angeles Fire Department was sending vehicles and helicopters around the city to identify damages, says Brian Humphrey of the Los Angeles Fire Department.
