In 1954, the state of Nevada was struck by a series of earthquakes that began with three magnitude 6.0+ events in July and August that preceded the Mw  7.1–7.3 mainshock and M 6.9 aftershock, both on December 12. All five earthquakes are among the largest in the state, and the largest since the Cedar Mountain earthquake (M 7.2) of 1932 and Pleasant Valley event (Ms  7.7) in 1915. The earthquake was felt throughout much of the western United States.
