Abstract:

A list of seismic events for the period 20 February to 19 March 1972 The International Seismic Month - ISM has been compiled using short-period data from a large number of seismic stations and arrays. Hypocenters and other parameters have been obtained for every event and are presented along with comparisons with other event lists for the same time period. Also included are the results of experiments designed to calibrate certain parameters which have been selected to indicate the accuracy of estimated depths and epicenters. The ISM list contains 996 verified events.
