— When a meteoroid passes through the Earth's atmosphere, it may generate acoustic waves in the form of a conical shock front and again in an explosive terminal burst. These acoustic waves reach the ground and their arrival times may be recorded on seismograms. Equations are given (with numerical examples, and for various atmospheric models) to recover the track of the meteoroid, and possibly the meteorite, from times of arrival at the seismographic stations.
