Seismicity of the United States, 1568-1989
Seismicity of the United States, 1568-1989
This publication (USGS PRofessional Paper 1527) is a history of the principal earthquakes in the United States from 1568 through 1989.
It contains all pertinent information on the date, location, size and effects of these historical events.
The authors have included only those earthquakes of Modified Mercalli intensity ("MM intensity" or "MMI") >= VI and Magnitude 4.5.
Exceptions are the State of Alaska and offshore areas of California, Oregon, and Washington, where the magnitude range was increased to >= 5.5 because of the high seismicity of those regions.
This publication supercedes the compilation by Coffman and others (1982), published jointly by the USGS and NOAA.
The publication is organized by state.
For each state, a tabular list of earthquake data is followed by a brief narrative of the damaging effects of each earthquake of intensity >= VI.
Isoseismal maps depicting the areal distribution of effects, and photographs of property damage and geologic effects complement the narratives of selected events.
