This paper presents an expert system that interprets seismic data from Norway's regional seismic array, NORESS, for underground nuclear weapons test ban treaty verification. Three important aspects of the expert system are (1) it emulates the problem solving behavior of the human seismic analyst using an Assumption Based Truth Maintenance System, (2) it acts as an assistant to the human analyst by automatically interpreting and presenting events for review, and (3) it enables the analyst to interactively query the system's chain of reasoning and manually perform and interpretation. The general problem of seismic treaty verification is described. The expert system is presented in terms of knowledge representation structures, assumption based reasoning system, user interface elements, and initial performance results. 8 refs., 10 figs., 2 tabs.
