The United States Geological Survey reports that more than two dozen earthquakes rattled the Lake Tahoe region early Tuesday.
The largest earthquake measured a magnitude 3.9 shortly after 2 a.m. at a shallow depth.
The earthquake was reported 11 miles (17 kilometers) from Truckee.
Preliminary earthquake information shows that at least 28 minor aftershocks occurred in the area, ranging in magnitude from 0.6. to 3.2 following the 3.9 magnitude shaker.
No major damage or injuries were reported.
The San Francisco Chronicle reports that a recent Berkeley Seismological Laboratory study indicates earthquake activity increases in the dryer season. Experts say more quakes occur this time of year, as the weight of all the snow and water begins to lift, allowing the crust to rise
