EARTHQUAKES IN THE UNITED STATES 1963-64 AND AN EVALUATION OF THE DETECTION CAPABILITY OF THE UNITED STATES SEISMOGRAPH STATIONS

Abstract

This study is based on earthquakes reported on the Preliminary Determination of Epicenter (P.D.E.) cards of the Coast and Geodetic Survey. Four types of presentations are made: (1) a chronological list of earthquakes: (2) a magnitude map showing the geographical distribution of earthquakes whose magnitudes are greater than, or equal to, 3.0; (3) a presentation of frequency versus magnitude for the total United States for and individual regions of high seismicity; and (4) a 'seismicity' map giving a quantitative measure of relative seismic activity.
