Abstract : This document describes the second phase in the development of a Global Association System to perform automatic interpretation of seismic data to associate signals from a network of stations and locate seismic events using a method similar to generalized beam forming E.G., Ringdal and Kvarna, 1989; Taylor and Leonard, 1992; Leonard, 1993. The major improvement over the first phase is the implementation of a new method to resolve conflicts among phases that are associated with more than one preliminary event hypothesis. This task was performed by a separate expert system called ESAL in the first phase Le Bras et aL, 1994a. This document also describes our design for the third phase of the Global Association System which will include the association of non-defining secondary phases and late-arriving data. (MM)
