3.5-Magnitude Earthquake Strikes Near Big Bear, California — Third Tremor Within Hours

A mild 3.5-magnitude earthquake struck near Big Bear Lake, California, early Sunday morning, shaking parts of the San Bernardino Mountains, according to the U.S. Geological Survey (USGS).

The quake occurred at approximately 3:40 a.m., about four miles north of Big Bear City. Despite the early hour, many residents in the area reported light shaking, though there were no immediate reports of injuries or significant structural damage.

This tremor marked the third small earthquake in the region within just a few hours, with all three quakes centered within a five-mile radius. The cluster of quakes suggests increased seismic activity in the Big Bear fault zone, which occasionally experiences minor earthquakes due to its proximity to the San Andreas Fault system.

Experts note that earthquakes of this magnitude are typically considered light, rarely causing serious damage but often serving as reminders of the region’s seismic vulnerability.

Residents are encouraged to stay prepared with emergency kits, review household safety plans, and secure heavy furniture in case of larger quakes in the future.

Key Details:

• Magnitude: 3.5
• Location: 4 miles north of Big Bear City, California
• Time: 3:40 a.m. Sunday
• Depth: Shallow (USGS data)

While the recent activity near Big Bear Lake hasn’t caused harm, it reinforces the importance of earthquake preparedness across Southern California.
