A magnitude-4.6 earthquake struck Southern California on Friday, causing widespread shaking and numerous aftershocks. The quake, which hit just northwest of Malibu in the Santa Monica Mountains, was felt across the greater Los Angeles area, potentially affecting up to 12 million people. Despite the intensity of the quake, there were no immediate reports of significant damage, and standard procedures were followed to assess any potential impacts. The earthquake possibly occurred along the Malibu Coast Fault, underscoring Southern California’s susceptibility to seismic activity. Coincidentally, the quake struck on the same date as the deadly 1971 San Fernando earthquake, reminding the region of its seismic vulnerability and the importance of preparedness. In addition to the Southern California earthquake, a magnitude-5.7 quake rattled Hawaii’s Big Island, causing tremors felt as far as 200 miles away on Oahu. However, this event was unrelated to the seismic activity in Southern California. The earthquake reinforced the significance of ongoing monitoring efforts and prompt response measures in ensuring the safety and resilience of communities in earthquake-prone regions.
