Magnitude 2.5 Earthquake Shakes Napa Area
NAPA (CBS SF) -- A magnitude 2.5 earthquake struck east of Napa Wednesday morning.
The quake struck at a depth of six miles about four miles east of Napa shortly before 8 a.m.
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.
At least five people reported feeling the shaking on the USGS website.
