While various technologies, including seismology, are essential for monitoring atmospheric and underwater explosions, seismology provides the primary means for monitoring underground nuclear explosions. In many cases, seismic waves from buned explosions can be recorded by global networks of seismometers, and the signals used to detect, locate, and identify the source of the disturbance (allowing nuclear explosions to be distinguished from conventional chemical explosions or natural earthquakes)

. This system is focused on nuclear monitoring and is neither designed nor intended to replace any existing international efforts for earthquake monitoring or data acquisition for basic science applications.

Each ISMS-NDC may have responsibilities for providing its nation's primary and auxiliary station data to the ISMS-TDC, retrieving seismic data and event parameters from the TSMS-IDC, and servicing internal verification functions. For the United States, it is likely that some of the additional national and multilateral data, combined with ISMS data in national verification Unctions, will be classified, as will the final nuclear monitoring event list.

The entire system involves data acquisition, data archival, and data processing, but no data distribution. A classified event bulletin with source-type discrimination and yield estimation for suspected nuclear tests has been the primary product ofthis nuclear monitoring system.

Numerous international and national seismographic networks are involved, ranging from isolated stations to dense regional networks of short-period seismometers to sparse global networks of broadband seismometers. Thousands of seismic stations contribute data to the global system, as illustrated by a map of stations contributing data to the International Seismic Centre (TSC)

While production of definitive bulletins of event parameters on time scales of days to years is one of the primary objectives of the earthquake monitoring system, rapid location and analysis of earthquakes are important for emergency response and hazard mitigation (NRC Real-Time Seismology, 1991, Heaton et al., 19891. These efforts have increased the requirement for real-time data processing of both regional and global seismic data for activities of both the National Oceanographic and Atmospheric Administration (NOAA)

There is now no technological excuse for this underutilization of data, because digital seismic data can readily be archived in efficient data management systems that allow multiple users to access the data, independent of their primary objectives. Thus, ISMS data can be combined with existing seismic databases to the benefit of earthquake analysis and investigations of the deep interior of Earth as well as hazard studies and nuclear test monitoring.
