Morgan Hill, California Earthquake, April 1984
The Morgan Hill earthquake, a moderate-size ( M g =6.1, M L =6.2, M=6.2) event, was felt throughout central California on April 24, 1984. The epicenter of the earthquake was located near Halls Valley southwest of Mount Hamilton, and the event is presumed to have occurred on the Calaveras fault. Damage, however, was concentrated near the south end of the Anderson Reservoir and in the town of Morgan Hill. A preliminary assessment by the California Office of Emergency Services estimated damage to private property at \$7.0 million and to local-government facilities at \$0.5 million, for a total of \$7.5 million in damage.
