A Body Wave-Surface Wave Seismic Discriminant at Very Close Distances

Abstract

We summarize contract work in connection with seismic discrimination. We have attempted to find a body wave-surface wave discriminant based on close-in data of NTS events. This endeavor now seems difficult to attain. We have done supporting work in terms of data recovery (high-quality digital data records of about 100 earthquakes and several nuclear explosions), extension of existing explosion source theory (to try and explain how, for a single explosion, the time history could appear different at different distances), and in creating theoretical seismograms for comparison with close-in (8 km) accelerometer data.
