Frequency-Dependent Short-Period Explosion Coda Amplitudes in Northern Eurasia
Abstract
Travel-time and magnitude-yield calibration of Northern Eurasia, which is largely aseismic, can be improved by using the large chemical and peaceful nuclear explosion (PNE) seismic data sets acquired by the Soviet deep seismic sounding (DSS) program. Eleven major data sets of this program have recently been digitized and have become available to nuclear test monitoring research. Although the PNEs have been already used in several monitoring studies, the chemical-explosions data sets are still incompletely explored. In the present study, we use inversion and numerical modeling to analyze the coda amplitude parameters and P-wave travel times from numerous DSS explosions, which could lead to a detailed empirical mapping of seismic properties within northern Eurasia.
