High-Frequency Spectra of Earthquakes and Explosions

Abstract

Existing seismic earthquake and explosion data have been analyzed as part of the near-field earthquake program. Source characteristics of small magnitude events were investigated to better understand earthquake/explosion discrimination techniques. Coda spectral analysis was found useful in determining source parameters from high-frequency data. Because of the large influence of path effect on spectral shape, the use of body wave data was found to present greater difficulties. Source parameters did not seem to be significantly different for explosions and earthquakes. Site location generally had a strong effect on source characteristics.
