Compressional Wave Power Spectrum from Seismic Sources
Abstract
The power spectra and waveforms of P-wave signals are studied using large aperture seismic array data. P-wave pulse lengths and attenuation are determined by deconvolution of records to earth displacement, and by comparing spectral shapes with predictions from source models. A least-square procedure is used to fit predicted spectra to observations by varying model parameters. In a classification experiment using statistical limits derived from NORSAR data and pulse widths measured at LASA, classification capability intermediate between the 'spectral' discriminant LTM and the m sub b - M sub s discriminant was achieved, without any regional corrections.
