An earthquake measuring 3.8 in magnitude shook Malibu and the Westside of Los Angeles early Friday afternoon, as reported by the U.S. Geological Survey. The epicenter of the tremor was approximately 4.6 miles north of Point Dume, situated in the mountainous region above Malibu. This marks the seventh seismic event recorded in this area this year.
The U.S. Geological Survey categorized the shaking as “weak,” or Level 3 on the Modified Mercalli Intensity Scale, which could be felt across Malibu, Thousand Oaks, Calabasas, Woodland Hills, Canoga Park, Winnetka, and Reseda. Such intensity is likely to be noticeable indoors, particularly on upper floors, causing slight rocking of stationary vehicles.
A lower level of shaking, Level 2, may have been perceived in other parts of the San Fernando Valley, as well as in Santa Monica and the broader Los Angeles Basin. This level of shaking typically registers with only a few individuals, particularly those on upper floors.
In an observation from Mar Vista, residents reported feeling the shaking for 10 to 15 seconds on the second floor of buildings, likening it to a light jolt as if someone had nudged a desk.
Interestingly, the 3.8 magnitude quake’s epicenter was just northeast of a more powerful quake that struck on September 12, which registered 4.7 and startled many, including the mayor of Malibu and television anchors. It was also located about six miles northeast of a 4.6 magnitude earthquake that caused property damage earlier in the year.
Seismologist Lucy Jones noted that Southern California has witnessed 15 independent seismic events this year where tremors reached a magnitude of 4 or more, marking the highest annual count in 65 years, surpassing the 13 recorded in 1988.
While the frequency of these seismic events is noteworthy, it does not provide clarity about when a potentially devastating earthquake might occur. The last significant quake to hit Los Angeles County, 30 years ago, was a 6.7 magnitude tremor that resulted in severe casualties and damage.
To prepare for future seismic activity, residents are encouraged to join newsletters focused on emergency preparedness, which cover essential topics ranging from earthquake kits to critical safety advice.
This emphasis on community readiness and awareness reflects a positive step toward ensuring safety in an earthquake-prone region. By staying informed and prepared, residents can mitigate the impacts of seismic events and enhance their resilience in facing whatever nature brings next.
