A cluster of earthquakes shook a secretive Navy base in the Mojave Desert on Thursday afternoon and before dawn Friday, geologists say.
Numerous small quakes hit in and around the Naval Air Weapons Station China Lake, according to the U.S. Geological Survey.
Five of the quakes were higher than 2.5 magnitude between 3 p.m. Thursday and 3:30 a.m. Friday in Ridgecrest, the USGS said.
