Near Field Small Earthquake Long Period Spectrum

Abstract

The authors compute displacement spectra of explosion and earthquake seismograms in an attempt to study source parameters. The explosion data are at odds with several recent source theories for explosions (e.g. flat P-wave spectra from .025 to 1.5 Hz). These data are consistent with a study of trans- Sierra earthquakes in that the spectral corner frequency appears to be controlled by the source time duration. These data should stimulate the investigation of source models for which the corner frequency measures the source time duration and not the source dimension.
