THE RELATIONSHIP BETWEEN SIGNAL AMPLITUDES AND SURFACE GEOLOGY AT THE TFSO EXTENDED ARRAY.

Abstract

A study of 48 teleseismic P waves recorded at six LRSM sites in Arizona shows a wide variance in the relative signal amplitudes among sites, although the mean amplitude at each site correlates very well with the seismic impedance of the stratum directly supporting the seismometers. A test indicates that this variability cannot be simply ascribed to differences in source or azimuth, suggesting that the amplitudes are reacting sensitively to changes in signal frequency and/or angle of incidence.
