The earthquake had a magnitude of 6.5 M L and a hypocentral depth of only 2.8 km (1.7 mi). Shaking was felt throughout California and Nevada, with some reports from as far as San Francisco, Los Angeles, and Salt Lake City. [7] [8] The estimated maximum intensity of shaking was rated as VIII (Severe) on the Modified Mercalli intensity scale.
Since the three damaging earthquakes that occurred in the American Midwest and the United States East Coast ( 1755 Cape Ann, 1811–12 New Madrid, 1886 Charleston) were well known, it became apparent to settlers that the earthquake hazard was different in California.
