Abstract : Seismic monitoring of a CTBT (Comprehensive Test Ban Treaty) will require analysts to review tens of events per hour recorded by networks of more than a hundred stations. Use of the traditional waveform display as the primary data display tool is incompatible with this requirement; traditional waveform displays are inefficient in their presentation of relevant data and place high demands on computer resources. Drawing on resident data visualization expertise and on our hands-on experience with the design and implementation of the ADSN (AFTAC Distributed Subsurface Network) system at AFTAC, we have designed a new system consisting of a hierarchical series of displays which present relevant information to the analyst in a more efficient manner. The displays are designed to be used in a top-down manner with the analyst starting with the most general display and proceeding to the most specific (the waveform display) only when it is needed. Testing to date has focussed on data from the GSETT2 (Group of Scientific Experts Technical Test #2) in 1991. Future efforts will be directed towards improved data sets from the ongoing GSETT3.
