TRUCKEE (CBS SF) — A 4.2 magnitude earthquake followed quickly by a 2.7 magnitude aftershock rumbled deep beneath the waters of Lake Tahoe off Dollar Point Friday morning.

The U.S. Geological Survey said the initial jolt took place at 8:25 a.m. and was epicenter in a region where the lake bottom is crisscrossed by faults about 5 miles from Dollar Point. The 2.7 magnitude aftershock followed at 21 minutes later and a larger 3.1 magnitude temblor at 9:04 a.m.

Two more followed, each temblor measuring a 2.8 magnitude.

The 4.2 quake was strongly felt in Tahoe City, Carson City, Nev., Truckee and Incline Village, according to USGS tracking.

A swarm of quakes measuring 3.7 magnitude and lower hit the same fault area in April with residents as far away as Sacramento reporting feeling the temblors. A 4.7 magnitude temblor also struck near Truckee on May 10.

Meanwhile, Mary posted: “I have friends that never felt an earthquake in their 40 year old lives in Sacramento that felt the last two in Tahoe. It’s super uncommon to feel them here.”

Patty Price said it jolted her awake.
