The 4 November 2014 Nevada quake is the largest one recently in a swarm of some 240 earthquakes of magnitude 2.0 or greater that have occurred in that area since July, 2014.
This was a 4.6-magnitude earthquake in northwestern Nevada Tuesday night. This earthquake is the largest one recently in an earthquake swarm that has been occurring in the sparsely populated northwest corner of Nevada, near the borders of Oregon and California, since July 2014. According to the Reno Gazette-Journal: There have been 240 earthquakes of magnitude 2.0 or greater in that area since July 12. The nearest homes are in Cedarville and Alturas in Modoc County, California … said A.J. McQuarrie, deputy director of Modoc County Office of Emergency Services. Only four people reported feeling the quake, with the nearest person in Cedarville, California, about 45 miles west.
Nevada ranks among the most seismically active States.
A number of the larger shocks have produced some spectacular examples of surface faulting; these include shocks at Pleasant Valley (1915), Cedar Mountain (1932), Excelsior Mountain (1934), Rainbow Mountain (1954), and Fairview Peak – Dixie Valley (1954). Although these events are classified as major earthquakes in terms of magnitude, no fatalities were reported and building damage was minimal because of the sparse population of the areas.
The earliest reported earthquake in Nevada occurred in 1851. A newspaper article in 1865 cited reports of an earthquake 13 years earlier near Pyramid Lake. The account stated that great cracks opened from which water spouted 100 feet high. Large landslides were also reported.
The 7.1-magnitude earthquake in Pleasant Valley, Nevada on October 3, 1915 is the largest known earthquake in Nevada, since records have been kept.
