A magnitude 3.8 earthquake struck Malibu and the Westside of Los Angeles around early Friday afternoon, as reported by the U.S. Geological Survey. The epicenter of the quake was located approximately 4.6 miles north of Point Dume, situated in the mountains just outside Malibu’s city limits. Notably, this event marks the seventh earthquake to occur in this region this year.
The shaking, classified as “weak” on the Modified Mercalli Intensity Scale (Level 3), was felt in various locations including Malibu, Thousand Oaks, Calabasas, Woodland Hills, Canoga Park, Winnetka, and Reseda. Such intensity is generally noticeable indoors, particularly on upper floors, with the potential to cause minor rocking of stationary vehicles.
A lower intensity of shaking, classified as Level 2, was experienced across other areas in the San Fernando Valley, Santa Monica, and the broader Los Angeles Basin. This level is typically perceived only by a few individuals at rest, mostly on upper floors of buildings. In Mar Vista, those on the second floor reported feeling the tremor for about 10 to 15 seconds, akin to the sensation of someone lightly shaking a desk.
Friday’s quake occurred roughly three-fifths of a mile northeast of a more significant magnitude 4.7 earthquake that rattled the area on September 12. That previous quake startled residents and even led the mayor of Malibu and his wife to take cover beneath their kitchen table. Additionally, it was located approximately six miles northeast of a magnitude 4.6 earthquake from February 9, which had strong enough effects to dislodge items from counters and cause structural damages.
According to seismologist Lucy Jones, Southern California has witnessed 15 distinct seismic sequences this year, each with at least one earthquake of magnitude 4 or greater. This figure is the highest recorded in 65 years, surpassing 1988’s count of 13. However, this increase in seismic activity does not indicate when a major destructive earthquake might occur next; the last substantial quake in Los Angeles County was 30 years ago, resulting in significant casualties and damage.
In an effort to enhance preparedness for potential future earthquakes, residents are encouraged to join the “Unshaken” newsletter, which features essential information on emergency readiness, earthquake kits, and critical safety advice.
This situation serves as a reminder for the Los Angeles area to remain vigilant and prepared for seismic activity. Regular updates and educational resources can bolster community resilience amidst these natural events, fostering a sense of security and awareness among residents.
