A Comparative Study of Two Azimuth Based Non Standard Location Methods
Abstract
Two non-standard, independently developed, azimuth-based seismic triangulation procedures are evaluated. The goal is to develop ad hoc algorithms which can effectively tackle the seismic location problem under the following difficult yet realistic situations often encountered in seismic monitoring for the purposes of hazard reduction as well as for the underground nuclear explosion monitoring: 1) the crustal model is not known, and hence an arbitrary global model may have to be utilized; 2) the seismic network is not calibrated, and hence the phase arrivals will be used as they are without any station-specific or path-specific correction; and 3) the azimuthal coverage of the recording stations is poor.
