Previous studies have shown a variety of atmospheric disturbances (e.g., sonic booms, meteoroid falls, thunder, and explosions) can be detected by a seismograph if the acoustic pressure wave energy is sufficiently strong. Kanamori et al. (1991) and Cates and Sturtevant (2002) used the seismic network in southern California to study sonic booms generated by the space shuttle and aircraft. Ishihara et al. (2003) used seismic data from a dense seismographic array in the northeastern region of Honshu Island, Japan, to determine the trajectory of a meteoroid. Kappus and Vernon (...
