A magnitude 4.1 earthquake off the Los Angeles County coast brought weak shaking throughout Southern California on Monday.
The temblor, which occurred at 8:27 a.m., was felt throughout Los Angeles, Orange and Ventura counties, according to earthquake sensing instruments and residents reporting what shaking they felt to the U.S. Geological Survey’s Did You Feel It? website.
The weak shaking felt across the region is defined by the Modified Mercalli Intensity Scale as being felt noticeably by people indoors and rocking standing motor vehicles slightly.
The earthquake epicenter was about 10 miles southwest of San Pedro, 11 miles southeast of Rancho Palos Verdes, 16 miles southwest of downtown Long Beach, and 16 miles northwest of Avalon on Santa Catalina Island.
An average of five earthquakes with magnitudes between 4.0 and 5.0 occur per year in the greater Los Angeles area, according to a recent three-year data sample.
Seismologist Lucy Jones on social media wrote that the New Year’s Day earthquake was “not near any known fault” and “way too small to even talk about tsunamis.”
The California earthquake was “completely unrelated to Japan,” Jones wrote. Western Japan endured its own New Year’s Day earthquake, occurring just after 4 p.m. local time. The largest quake was a magnitude 7.5 and rocked a region about 190 miles northwest of Tokyo, 190 miles northeast of Kyoto and 160 miles northeast of Nagoya.
The strongest shaking in Japan was in Ishikawa prefecture, along the narrow Noto Peninsula that extends off the western Japanese coast. The Associated Press said buildings collapsed and a fire was started in Wajima city, and local news organizations said deaths have been reported.
Japanese broadcaster NHK published a photo of a structure that was believed to be a seven-story building that toppled over in the earthquake. Elsewhere in Wajima, more than 100 buildings are believed to have burned, NHK said, with at least eight deaths reported in Ishikawa.
