Southern California experienced a sudden jolt Monday morning when a noticeable earthquake rippled across the region, reaching from San Diego to Los Angeles. The shaking struck shortly after 10 a.m. Pacific Time, with early estimates placing it in the moderate magnitude range. Centered a few miles south of Julian, the quake was strong enough to sway buildings and momentarily disrupt daily routines across multiple counties.

Emergency alerts were quickly sent to residents, reinforcing standard earthquake safety guidance and urging calm awareness. In the hours that followed, seismologists recorded several aftershocks, the strongest measuring below magnitude 4. Despite the broad reach of the shaking, officials reported no serious injuries, and early assessments indicated that damage to buildings and infrastructure was minimal.

Some localized impacts did occur. Small rockslides briefly affected portions of State Route 76, and a handful of businesses reported minor issues such as fallen merchandise or short interruptions. State and city leaders, including California Governor Gavin Newsom and San Diego Mayor Todd Gloria, confirmed they were closely monitoring developments. San Diego State University also announced that its campus remained unaffected and continued normal operations.

Transportation agencies took precautionary steps as well. Metrolink temporarily paused train service between Oceanside and San Clemente to inspect tracks before safely resuming operations. Residents have been advised to stay alert for potential aftershocks and to review emergency preparedness plans. While the earthquake caused understandable concern, the limited damage and coordinated response underscored Southern California’s ongoing emphasis on readiness and public safety.
