DownloadThe 2014 South Napa earthquake struck on August 24, 2014, registering magnitude 6.0 (moment magnitude, Mw).
Its epicenter was located near 38.22°N, 122.31°W, at a depth of about 11 km — a shallow crustal earthquake. Shallow earthquakes like this release their energy close to the surface, which is why the shaking near the epicenter was so violent.
An estimated 1 person was killed.
