A magnitude 3.8 earthquake shook Malibu and the Westside of Los Angeles early Friday afternoon, as reported by the U.S. Geological Survey. The epicenter was located approximately 4.6 miles north of Point Dume, situated in the mountains that border Malibu’s city limits. This event marks the seventh earthquake recorded in the region this year.
The earthquake prompted “weak” shaking, rated Level 3 on the Modified Mercalli Intensity Scale, which may have been felt in areas such as Malibu, Thousand Oaks, Calabasas, Woodland Hills, Canoga Park, Winnetka, and Reseda. Although classified as weak, this level of shaking can be noticeably felt indoors, particularly on upper floors, and may cause slight movement in parked vehicles.
In the broader San Fernando Valley, Santa Monica, and across the Los Angeles Basin, residents likely experienced Level 2 shaking, generally felt by only a few individuals, especially on upper levels of buildings. In Mar Vista, those on the second floor felt the tremors lasting between 10 to 15 seconds, comparable to the sensation of someone nudging furniture.
Notably, Friday’s quake had its epicenter just northeast of a stronger magnitude 4.7 earthquake that struck on September 12, which had significant psychological and physical impacts on residents, including Malibu’s mayor, who took cover at home. Additionally, it was about six miles from a magnitude 4.6 quake earlier this year that reportedly knocked items off counters and damaged property.
Seismologist Lucy Jones noted that Southern California has witnessed 15 notable seismic events this year, each with at least one magnitude 4 or higher earthquake. This surpasses the previous record for the highest annual count in 65 years, which was 13 in 1988. However, the increased seismic activity does not indicate when a larger, damaging earthquake may occur. The last major quake in Los Angeles County was three decades ago, resulting in severe damage and loss of life.
As Southern California continues to experience seismic fluctuations, residents are encouraged to prepare themselves for potential future quakes. To aid in preparation, the community can subscribe to an informative newsletter, “Unshaken,” which offers guidance on emergency preparedness in easily digestible segments.
While it can be alarming to experience earthquakes, this event can also serve as a timely reminder of the importance of being prepared for natural disasters. By taking proactive steps, residents can enhance their safety and resilience in the face of seismic activity.
In summary, the magnitude 3.8 earthquake in Malibu and the Westside of Los Angeles serves as a wake-up call for preparedness and awareness, emphasizing the need for safety measures against potential future seismic events.
