Abstract : This Final Report describes the Global Association System for automatic interpretation of seismic data to associate signals and locate seismic events. It includes results for a synthetic data set intended to represent the type of global network that is planned for the upcoming Group of Scientific Experts Third Technical Test called GSETT-3 (for an overview, see Kerr 1993), and actual data from the prototype U.S. National Data Center (PNDC) at AFTAC. This system uses a hybrid method that integrates techniques in generalized beam forming E.G., Ringdal and Kvoerna, 1989; Taylor and Leonard, 1992; Leonard, 1993 and expert systems Bache et. el., 1993. It is designed to handle the large volumes of data that are needed to monitor compliance with a Comprehensive Test Ban Treaty (CTBT).
