Explosion Generated Seismic Waves
Abstract
The mechanisms of generation of SH and Love waves by underground nuclear explosions are investigated theoretically and experimentally. An explosion in pre-stressed medium is formulated as a composite source consisting of an isotropic explosion and a double-couple representing the tectonic strain release. From the radiation patterns of Rayleigh waves and Love-to-Rayleigh wave amplitude ratios relative strength of the strain release component is determined. It is found that relative amplitudes of Love waves and tectonic strain energy release strongly depend on the medium properties in the immediate vicinity of the explosion.
