A magnitude-5.2 earthquake was recorded near the mountain community of Julian in San Diego County late Monday night, and the movement was noticed across parts of Southern California. The event occurred shortly after 11 p.m., creating a brief jolt followed by light rolling motion that many residents identified immediately. People from San Diego to Los Angeles mentioned feeling their windows vibrate and seeing light fixtures sway gently.
Although the movement was strong enough to get the attention of many households, local officials reported no significant damage. Community members quickly shared their experiences online, comparing what they felt and checking in with one another. As a routine step, crews reviewed key areas such as roads, bridges, and utility systems to ensure everything was functioning normally.
According to the U.S. Geological Survey, the activity originated at a depth of around eight miles, which can make moderate seismic events feel more noticeable. Many residents also received a notification through California’s ShakeAlert system, which issued a brief alert moments before the shaking reached them. These early messages are designed to give people a few seconds to steady themselves and take simple protective steps.
State officials noted that ShakeAlert continues to be a helpful tool for public awareness. As experts observe the area for possible follow-up activity, authorities are reminding residents to stay mindful of basic preparedness guidelines. Because California regularly experiences natural ground movement due to its location along major fault zones, staying informed and maintaining simple readiness plans can help communities feel more confident and secure.
