A 5.2 magnitude earthquake hit Southern California on Monday morning, sending seismic waves across the region. The epicenter was located near Julian, about 60 miles east of San Diego. Occurring at 10:08 a.m., the quake was followed by several aftershocks. Initial reports indicate that there were no major injuries or structural damage. Local authorities are working quickly to assess the situation.

Location and Depth of the Southern California Earthquake
The earthquake’s epicenter was just south of the town of Julian, situated in the Elsinore Fault zone. The 5.2 magnitude earthquake struck at a depth of approximately 8 miles. While the tremor was felt across a wide area, experts believe the impact was mitigated by the relatively shallow depth of the quake.
Aftershocks and Ongoing Seismic Activity in Southern California
Following the 5.2 magnitude earthquake, numerous aftershocks, some with magnitudes over 3.0, were felt in the hours that followed. Aftershocks of this size are typical after significant seismic events. The National Weather Service assured the public that there was no risk of a tsunami along California’s coastline, which further alleviated concerns.

Expert Analysis on the Southern California Earthquake
Pat Abbott, a geology professor at San Diego State University, shared insights with FOX 5/KUSI, confirming that the 5.2 magnitude earthquake was expected along the Elsinore Fault. Abbott reassured the public that while the tremor was noteworthy, it was not unusual for the region. He also mentioned that the dry conditions this rainy season helped minimize the chances of rock or mudslides following the earthquake.

California Authorities Respond to the Earthquake Event
Governor Gavin Newsom’s office stated that he had been briefed on the earthquake and that state officials are collaborating with local governments to assess any potential damage. Meanwhile, Metrolink, the regional train service connecting Los Angeles and San Diego, temporarily suspended service for track inspections as a safety precaution.
Precautionary Measures Taken by the City of San Diego
In response to the 5.2 magnitude earthquake, the City of San Diego implemented precautionary measures, such as closing its administration building for the day. As a result, a scheduled city council meeting had to be moved to another location. These steps were taken to ensure the safety of city staff and the public during this seismic event.
