Shaking was felt all along the coast, from the San Luis Obispo area to the north to San Clemente in the south. Residents in the Los Angeles area and beyond as Southern California saw its largest quake in more than four years. There were no immediate reports of injuries or damage, on any of the islands, according to law enforcement and fire agencies across Southern California.
The quake did cause some minor landslides and earth movement on Santa Cruz Island, which was close to the epicenter. For those working in high-rise buildings, the shaking was more intensely felt. Some people in the Los Angeles area received about a 10-second warning before the shaking hit thanks to the state’s earthquake early warning system, according to seismologists at the California Institute of Technology. “It’s a regular sort of earthquake that we expect somewhere in Southern California,” Southern California Earthquake Center Director John Vidale told to media. There is a 1-in-20 chance that Thursday’s quake will lead to a larger one in the next few weeks. The early-warning system is under development by the USGS and is available only to a limited array of testers, but it is expected that more people will be eligible to test the system later this year.
