Last month’s strong earthquakes in Ridgecrest, California caused major damage to Naval Air Weapons Station China Lake. It will cost $5.2 billion to repair the facility where advanced weaponry is tested. 20% of the buildings on the base are considered unsafe. Repairs are needed for an air traffic control tower, hangars, a laboratory, a gym and a pool. The base is near the epicenter of 6.4 and 7.1 magnitude earthquakes that struck July 4th and 5th, followed by dozens of strong aftershocks.
