Abstract:

This report reviews our AFTAC funded research over the last two years. The principal objective of our research was to investigate the utility of time varying spectral estimates obtained from regional seismic records for distinguishing mining events from single explosions and earthquakes. A second goal of this research program was the exploration of additional small-event discrimination techniques which might be merged with the time-frequency method. The emphasis was on acoustic and low-frequency seismic techniques.
