DOE Program on Seismic Characterization for Regions of Interest to CTBT Monitoring,

Abstract

The November 1993 transfer of responsibility to the Department of Energy (DOE) for part of the Defense Department's research in support of a Comprehensive Test Ban Treaty (CTBT) has led to a significant reorientation of the DOE seismic research effort, with significant new efforts on Geophysical Characterization of the Middle East-North Africa (ME-NA) and Southern Asia (SA) regions, respectively guided by Lawrence Livermore National Laboratory (LLNL) and Los Alamos National Laboratory (LANL). These programs will provide detailed regional calibrations that can be used to improve seismic phase identification, association, event location and event identification. Parameters and other information generated by these efforts will be incorporated into the knowledge bases of the Prototype National Data Center (PNDC) operated by the Air Force Technical Applications Center (AFTAC), and the Prototype International Data Center (PIDC) being developed by the Advanced Research Projects Agency (ARPA). Knowledge required for improved automated data processing by the PNDC and PIDC includes detailed, region-specific parameter sets related to traveltime, attenuation and frequency content of the various seismic phases that record at regional distances, plus information on seismicity, location and blasting practices of operating mines, structure of the lithosphere, topography and other data. For stations of the primary CTBT monitoring network, this information will be path-specific, with calibration parameters determined for the receiver sites, the source-receiver paths to potential source areas around the station, and the source areas. Insofar as possible these data will be formatted for direct incorporation into the knowledge base system of the data centers.
