A series of earthquakes, including two measuring 3.5, shook the Big Bear area overnight.
The first temblor – a 3.5-magnitude – struck around 11:15 p.m. Saturday 7 kilometers (roughly 4.3 miles) north of Big Bear City at a depth of 6.6 kilometers (4.1 miles), according to the U.S. Geological Service.
Nearly four hours later, a 3.4-magnitude quake struck the same area at 2:51 a.m. Sunday. About 40 minutes after that, another 3.5-magnitude rattled the same spot yet again, USGS data shows.
All was quiet until around 5:54 a.m. when a 2.5-magnitude quake struck. At 6:20, a fifth event – a 2.6-magnitude – was recorded, per USGS.
The epicenters of all five earthquakes were centered around Burnt Flat, per USGS mapping data. The area is very remote and mountainous.
There were no reports of any injuries or damage to any structures as a result of the five quakes.

Thousands of earthquakes are recorded in California each year, but the vast majority are extremely minor. Several hundred reach a magnitude of 3.0, and only about 15 to 20 reach a magnitude of 4.0 or greater, according to the USGS.
In North America, only Alaska records more quakes per year than California.
What to do in an earthquake
During an earthquake, knowing the proper steps to protect yourself and minimize injury is crucial. The California Department of Public Health (CDPH) provides detailed guidelines on what to do during such events. Here are the key points:
Drop: Immediately drop down onto your hands and knees. This position prevents you from being knocked over and allows you to stay low and crawl to safety if necessary.
Cover: Use one arm to protect your head and neck, and if possible, take shelter under a sturdy table or desk. If no shelter is available, get down next to an interior wall away from windows. Stay on your knees and bend over to protect vital organs.
Hold On: Hold on to your shelter until the shaking stops. Be prepared to move with your shelter if it shifts.
