On March 3, 2025, at 06:13 UTC, a magnitude 3.9 earthquake struck 2 km east-southeast of North Hollywood, California. The earthquake occurred at a depth of 15.3 km, as reported by the California Integrated Seismic Network (CISN) and the United States Geological Survey (USGS).

Location and Impact

  • Epicenter Coordinates: 34.163°N, 118.356°W

  • Depth: 15.3 km

  • Intensity Level: IV (Light shaking reported)

The earthquake was felt widely across the San Fernando Valley, including areas such as Burbank, Studio City, and Glendale. While there have been no reports of major damage or injuries, light shaking was reported by residents.

The ShakeMap Intensity Model recorded the event as Intensity IV, meaning that the tremor was felt indoors by many but unlikely to cause structural damage. The "Did You Feel It?" system, which gathers citizen-reported data, has recorded multiple responses from Los Angeles residents, further confirming light to moderate shaking across the region.

Seismic Activity in Southern California

This earthquake is part of ongoing seismic activity in the Los Angeles Basin, a region known for its complex fault systems. The area has experienced several small quakes in the past month, but this 3.9 magnitude tremor is the strongest recorded in the region in recent weeks.

Expert Analysis

According to Caltech Seismologists, no immediate aftershocks have been reported, but residents are advised to stay prepared for potential smaller tremors. The USGS and local authorities continue to monitor seismic activity in the region.

Preparedness Recommendations

Experts advise that residents of earthquake-prone areas take the following precautions:

  • Ensure emergency kits with food, water, and medical supplies are readily available.

  • Secure heavy furniture and items that could fall during an earthquake.

  • Familiarize yourself with the Drop, Cover, and Hold On technique to protect yourself during future seismic events.

  • Sign up for earthquake alerts, such as the MyShake App, which provides early warnings.
