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.”
