Swarm of earthquakes, including magnitude 6.0 quake, felt across NorCal
Several earthquakes rattled Northern California within minutes of each other Thursday afternoon, according to the United States Geological Survey.
Between Walker and Coleville in Mono County, about 23 miles southwest of Smith Valley, Nevada, a magnitude 6.0 earthquake was recorded around 3:50 p.m. Since that quake, the USGS has reported several other shakes either in Nevada or across the state border in Mono, Tuolumne and Alpine counties.
The earthquake was originally reported as magnitude 5.9 but was since revised to 6.0 around 5:45 p.m. by the USGS.
An earthquake in Farmington in San Joaquin County was originally reported by the USGS but that entry was since taken off the list of recent quakes. California seismologist Dr. Lucy Jones explained automatic systems that locate quakes sometimes get confused, especially if there are not many stations in the area.
