The objective of this work is to update, analyze, and document data for the Middle East and North Africa regions in order to provide accurate input to the DOE's Knowledge Base system. Specifically, we aim to provide assessments and comparison of different geophysical databases, such as Moho and basement maps, for the region of study, in an effort to document the accuracy and the extent and magnitude of the discrepancies. Additional "ground truth" information, primarily based on satellite information, for distinguishing mine-related activity are also to be provided, both through analysis of existing data at Cornell, and where possible, through in-country sources. Another objective is to map characteristics of regional seismic wave propagation and to document velocity models for the Middle East using data available to Cornell University. To date, we have developed and delivered to DOE authorities (1) a complete crustal structure including detailed topography, sediment thickness, and Moho depth values for the entire Middle East and North Africa regions, (2) our regional seismic waveform attenuation characteristics results in the Middle East region, and (3) a comprehensive study of Moho and basement depth models for the region. We developed a new complete crustal model for the Middle East and North Africa regions. The final model includes topography, basement depth, and Moho depth values for the entire region. These models are justifiable and better represent the crustal structure in the Middle East and North Africa regions. These models will serve as a good starting point in geophysical studies in this region. We also conducted a comparative study of available Moho and basement data sets developed by different groups in these regions.
