Abstract : As the target date (end of 1996) for the completion of multilateral comprehensive nuclear test ban treaty approaches, it is essential for the 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 has been to collect and organize all available seismological, geophysical, and geological datasets for the Middle East and North Africa into a digital information system that is accessible via the Internet from Cornell and can be utilized by the International Data Center and by other ARPA/AFOSR/DOE/AFTAC researchers. We digitized many cross sections showing the depth to basement and Moho and crustal velocity and density structures. We also organized seismicity, focal mechanisms, and gravity data for most of the region. We digitized data from Egypt, Than, Thaq, Israel, Jordan, Syria, Lebanon, Saudi Arabia, and Morocco. We have also digitized key geologic features for the Middle East. All data are being stored in our Archnfo Geographic Information System. A new user interface has been developed in Arc Macro Language which allows easy display and analysis of the available data. We currently hold a comprehensive bibliography of all the relevant references in a computer database. We also developed WWW tools for easy access to some of our databases. The 'Profile Maker' and the 'Focal Mechanism Maker' are tools that allow any user to make crustal scale cross sections between two arbitrary points and focal mechanism maps using our Web page. Our Web address is 'http://www.geo.cornell.edu/geology/me^.na/main.html'.
