YOUNTVILLE (CBS SF) — The U.S. Geological Survey says a magnitude 2.6 earthquake has struck the Yountville area Wednesday afternoon.
The USGS says the quake’s epicenter was located 4 miles SSW of Yountville, and struck at a depth of six miles. 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.
Residents reported feeling the quake on the USGS site.
The quake struck at 3:12 p.m.

Strong earthquakes with an epicenter off the coast can trigger tsunamis, depending on the size and type of the fault movement. The Pacific Tsunami Warning Center tracks earthquake data for the West Coast.
