The Morgan Hill, California, earthquake of April 24, 1984

Bulletin 1639
Edited by: Seena N. Hoose



The Morgan Hill earthquake, a moderate-size (M_g=6.1, ML =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. Acknowledgments.--! appreciate the helpful suggestions of Joseph I. Ziony and Robert D. Brown, Jr. These studies were aided by the generous cooperation of the many landowners who permitted access to their properties.
