NAPA COUNTY (CBS SF) — The U.S. Geological Survey says a magnitude 2.5 earthquake has struck Napa County Monday morning.

The USGS says the quake’s epicenter was located 5 miles east of Yountville and struck at a depth of 5.7 mles. Deeper quakes are less noticeable while a shallow quake–in the 0 to 40 mile depth range–can feel much stronger than their actual reported magnitude. Quakes just below the earth’s surface, in the 0 to 10 miles range, can cause even more damage at lower magnitudes.

The quake struck at 5:54 a.m.

People as far as Sacramento and San Lorenzo reported feeling the quake, according to the USGS website. No damage was reported.

Last Thursday, a magnitude 4.1 earthquake struck Napa County, making it the largest quake to hit the Wine Country since a magnitude 6.0 struck the area last August.
