Relative Location of Explosions Using Surface Waves

Abstract

A method of relative location for explosions using Rayleigh waves is developed and tested. It involves cross correlating a wavetrain with a previously recorded signal from the same source region and determining a relative 'travel-time' from the peak in the cross correlation trace. Locations are fairly accurate, but do not compare with the precision obtained with body waves and relative travel-time corrections. A number of causes of errors are discussed, and it is estimated that a sophisticated application of this method would yield location comparable to relative travel-time locations for large events.
