Seismological studies: Final report
A good quality, high-frequency digital data set of earthquakes recorded at short hypocentral distances has been assembled in common formats. This data set was used to evaluate the source spectral P-wave falloff of the earthquakes and explosions compared to theoretical predictions. It was found that the earthquake data disagreed with the Archambeau relaxation source theory (which has a falloff proportional to ..omega../sup /minus/3/ beyond the corner frequency) for large moment events and was approximately in agreement with the Brune model with a falloff of ..omega../sup /minus/2/. The explosions were found to have less high frequency energy at 30 Hz than predicted by the Sharpe model. 50 refs., 4 figs., 1 tab.
