A LARGE-POPULATION LASA DISCRIMINATION EXPERIMENTATION

Abstract

Short-period data from the Large Aperture Seismic Array (LASA) has been used in the past to develop and evaluate single station seismic discriminants for events at teleseismic distances from the array. The long- period data from LASA has been used in conjunction with the short period data to evaluate the ability of a single station to identify events based upon the relative excitation of body phases and surface phases. The present report is devoted primarily to further studies of single station discriminants which have been measured for a large population of almost 200 events.
