Negotiators from more than 35 countries are attempting to formulate a nuclear test-ban treaty and delineate a system from monitoring compliance. This book covers: (1) the desirable characteristics and capabilities of seismic monitoring stations; (2) recommendations on the flow paths and handling of the data, which are to be unclassified; and (3) the types and extent of research that will be needed in the next decade. The primary focus of the book is to explore how basic seismological research and test ban monitoring can be mutually beneficial.
