A seismic event measuring 4.2 on the Richter scale rumbled through the mountainous regions to the east of Los Angeles, causing tremors in various communities across Southern California. The epicenter of the earthquake was pinpointed to Lytle Creek, nestled within San Bernardino County's expanse, situated in the San Gabriel Mountains approximately 60 miles northeast of downtown Los Angeles. Initially estimated at a magnitude of 4.6, the seismic activity was later revised to 4.2.
Despite the notable quake, there have been no immediate reports of injuries or damages. However, widespread shaking was felt across several areas, including Long Beach, Carson, sections of the San Fernando Valley, Riverside, San Bernardino, and segments of Orange County.
Notably, the quake struck near the convergence point of the San Andreas and San Jacinto earthquake faults, adding to the seismic significance of the event. This area had previously experienced a magnitude-5.2 earthquake in 1970, which was preceded by a magnitude-4.1 foreshock just 20 minutes earlier. The impact of the seismic activity in 1970 caused disruptions, including knocking a radio station off the air and triggering mudslides and rockfalls that obstructed roads.
