abstract

A tabulation has been made of approximately 850 earthquakes, in Washington State and near its borders, between 1841 through 1965. This list was compiled from previously published scientific reports, newspaper accounts, and unpublished epicenter computations from the University of Washington Seismograph Station. Shocks of intensity V or less are not complete prior to about 1900 because of sparse population making reporting incomplete. There appears to be an increase of larger intensity and magnitude earthquakes since 1936 in Washington State, and especially in the Puget Sound area since 1949.
