Strong 5.2 Quake Hits San Diego County, Triggers Widespread Shaking in Southern California.
5.2 Magnitude Earthquake Shakes San Diego County, Felt Across Southern California
Southern Californians were jolted Monday morning when a magnitude 5.2 earthquake struck near Julian, a small mountain town in San Diego County famed for its apple pies, at approximately 10 a.m. local time. The tremor, centered 35 miles northeast of San Diego and 120 miles south of Los Angeles, rattled shelves, swayed light fixtures, and sent cups tumbling at businesses like the Julian Cafe & Bakery. “Everything is OK,” reassured owner Riley Ozuna, though the quake was felt as far north as Los Angeles.
Low Risk of Damage, But Risks Remain
The U.S. Geological Survey (USGS) reported a low likelihood of significant damage or injuries, noting that most structures in the region are built to withstand shaking. However, vulnerabilities such as landslides and soil liquefaction—a phenomenon where ground turns fluid-like during intense shaking—remain concerns. San Diego County authorities, including police, sheriff’s deputies, and local firefighters, confirmed no immediate reports of damage or emergencies.
Shake Alert System Put to the Test
The quake triggered California’s “Shake Alert” system, delivering warnings via cell phones, Android devices, and emergency broadcasts seconds before shaking began. Residents near San Diego, roughly 40 miles from the epicenter, received about 14 seconds of advance notice to “drop, cover, and hold on.” Operated by the USGS, the system aims to mitigate risks during seismic events.
Governor Gavin Newsom stated on social media that he was coordinating with local responders to assess potential needs but emphasized no major impacts had yet been reported.
Aftershocks Follow Earlier Tremor
Monday’s quake marked the second seismic event in the area within hours, following a magnitude 3.5 tremor Sunday afternoon. Minutes after the 5.2 quake, Julian experienced two aftershocks—magnitude 3.0 and 2.5—underscoring the region’s persistent seismic activity.
While the event caused minimal disruption, it served as a stark reminder of California’s earthquake risks and the critical role of preparedness systems in safeguarding communities.
