Eppley, R. A., et al., No. 41-1 
Publication Date: Part 1, 1965; Part 2, 1966 
Location: The 50 states and their immediate vicinity 
Period of Coverage: Both parts were revised to contain data from the 
earliest times to the close of 1963. 
Contents: This publication covers the most important earthquakes of the 
United States. It is composed of two parts. The first part is subdivided 
into seven regions: New England and New York, the Eastern Region, the Central 
Region, the Western Mountain Region, Washington and Oregon, Alaska, and 
Hawaii. Part two contains earthquake information on California and western 
Nevada. 
The information on each region is divided into three sections. The first 
is a list of earthquakes which contains year, date, time, geographical 
location, longitude, latitude, and intensity (modified Mercalli) of the 
quake's epicenter. The affected area in square miles and the reporting 
authorities are also given. The second section gives a listing of major 
earthquakes. It includes a description or account of the quake. The third 
section gives a listing of intermediate and minor quakes. A brief description 
is given. All lists are given in chronological order. 
Additional Information: This publication was revised in 1973 to cover 
data through 1970. The two older volumes have 
been combined to make one volume. A supplement 
was then issued in 1982 to cover data from 1971 
to 1980. The 1973 revised edition and the 1982 
supplement were then combined to make one 
volume.
