The Boston College Institute for Scientific Research (ISR) has conducted innovative research using tools, analysis techniques, and database development to support the Air Force Research Laboratory s (AFRL) nuclear monitoring program. The innovative research objectives of this task have been directed toward applying waveform modeling techniques to earthquakes and explosions at locations of interest to the community where both teleseismic and regional waveform data are available. Moderate to large earthquake sources provide high resolution ground truth information for regional studies of earthquake and explosion phenomenology. Some of our major efforts included the New England Damage Experiment where the question of shear wave generation mechanisms for explosive sources was addressed. Another major effort included the determination of attenuation parameters in La Paz, Bolivia for improved seismic phase identification.
