A 4.1 magnitude earthquake off the coast of Los Angeles County caused weak shaking across Southern California on Monday morning. The temblor, which struck at 8:27 a.m., was felt in Los Angeles, Orange, and Ventura counties, according to earthquake sensing instruments and reports from residents.
Firefighters reported that the earthquake was felt in Pasadena, where the Rose Parade was taking place, but no injuries or damage were reported. The earthquake, according to the Modified Mercalli Intensity Scale, was defined as being noticeable to people indoors and causing slight rocking of standing motor vehicles.
The epicenter of the earthquake was located about 10 miles southwest of San Pedro, 11 miles southeast of Rancho Palos Verdes, and 16 miles southwest of downtown Long Beach. The earthquake was also reported to be completely unrelated to the earthquake that occurred in western Japan just after 4 p.m. local time. That earthquake, with a magnitude of 7.5, caused buildings to collapse and a fire to start, leaving the extent of the damage and any potential casualties unclear.
The USGS reported that the earthquake in Japan caused strong shaking in the cities of Toyama and Kanazawa, with less intense but still noticeable shaking in other areas.
