History

The settlement began as a farming community called Crumville in 1912, honoring James and Robert Crum, local dairymen. The first post office opened in 1941. By 1943, Ridgecrest had grown to 115 homes and 196 residents. NOTS (Naval Ordnance Test Station) was established in November 1943, providing a strong job base for the years to come.

Ridgecrest incorporated in 1963. During this era the growth of Ridgecrest was governed by the continuing needs of the high tech industries coupled to the Naval Air Weapons Station (NAWS) programs for testing arms and guidance systems.

1995 earthquake

The area, associated with the Eastern California Shear Zone, has in the past experienced numerous earthquake swarms, groups of several thousand quakes under magnitude 6.0 or so, often with no obvious mainshock. The 1995 Ridgecrest earthquake sequence started on August 17, when a magnitude 5.4 quake, centered 18 kilometers (11 mi) north of the town of Ridgecrest, shook the area and spawned over 2,500 aftershocks over the course of the following five weeks. Then, on September 20, 1995, the second large quake struck the area: it measured magnitude 5.8, and was at that time the largest earthquake to hit southern California since the 1994 Northridge earthquake.

2019 earthquakes

On July 4–5, 2019, Ridgecrest was associated with a series of earthquakes, including the largest to affect the area in decades, measuring 7.1 magnitude. The epicenter was about 10 miles northeast of Ridgecrest. The earthquake sequence started with a 4.0 quake 11 kilometers (6.8 mi) southwest of Searles Valley, then at 10:33 A.M. a 6.4 quake struck 12 kilometers (7.5 mi) southwest of Searles Valley. Over 1,400 aftershocks struck Searles Valley and Ridgecrest. On July 5, 2019, at 8:19 P.M., the magnitude 7.1 earthquake occurred, with the epicenter approximately 10 miles northeast of Ridgecrest.
