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.
