Analysis of Regional Distance Body Waves for Seismic Discrimination
Abstract
The role of seismology in monitoring non-proliferation and underground testing of nuclear weapons is one of discrimination of low-yield devices detonated in uncalibrated environments. Most of the monitoring will be done at regional distances, so it is essential to develop a detailed understanding of seismic phases which have traveled 100-1500 km. In this report we detail procedures for recovering source parameters of small earthquakes at regional distances, and develop an empirical database for large chemical explosions. Regional distances seismograms are often difficult to deterministically model. It is essential that regions of specific interest be 'calibrated' by developing an empirical understanding of propagation characteristics. To this end we have studied the seismotectonics and gross crustal structure characteristics of the Middle East and the Lop Nor (the northeastern corner of the Tarim Basin).
