Seismic and Infrasound Energy Generation and Propagation at Local and Regional Distances Phase 1 - Divine Strake Experiment.

摘要

Eleven single infrasound systems and six infrasound arrays were deployed at existing seismic sites in Utah in order to gather a comprehensive set of seismic and infrasound recordings from rocket motor explosions. These preliminary efforts have resulted in the identification of regular (over 21 recorded) and large (40,000-80,000 lbs) surface explosions at the Utah Test and Training Range (UTTR) of the Hill AFB. The rocket motor explosions occur about every week providing an opportunity to develop seismic and infrasound recordings under a wide range of atmospheric conditions. Cooperation with the AF provided the necessary atmospheric data needed for modeling and was supplemented by additional profiles collected by our consortium. Additional sources of infrasound such as mining explosions were also documented. Infrasound, seismic and atmospheric data recorded during this experiment that took place during the month of August 2007 are summarized in this final report. Limited preliminary analysis of the data is also included. The complete data set has now been delivered to the IRIS DMC.
