Abstract : It is essential for the CTBT monitoring efforts that multidisciplinary information on any given region is readily available and accessible in a digital, on-line format via electronic networks for use by concerned researchers and decision makers. Our objective is to collect and organize all available seismological, geophysical, and geological data sets for the Middle East and North Africa into a comprehensive Geographic Information System (GIS). In addition, we are producing original results, such as crustal structure beneath available broadband seismic stations, in areas where there is no available information. We are distributing the organized databases in ArcInfo GIS format and menu driven access tools and with a specially designed World Wide Web (WWW) server. Among the already collected digital data sets are detailed Moho and basement maps for the Middle East region, seismicity catalogs, focal mechanisms, and tectonic fault maps, mine locations, and various types of geophysics/geologic/geographic data for the region. We have also developed metadata to document the resolution and accuracy of the already organized data sets. The developed organized system and its efficiency in using and updating it will help CTBT researchers and decision makers to reach a conclusion in a very short time, including analyses of special (suspect) events and On Site Inspection efforts. Our World Wide Web address for data distribution is http://atlas.geo.cornell.edu.
