Abstract:

We have collected seismic, geologic gravity and other potential data to develop a model of North African lithosphere via an integrated approach. We have generated a Bouguer gravity map and modeled gravity data along 3 transects. Seismograms from Worldwide Standardized Seismograph Network Stations of magnitude greater than 4.9 earthquakes occurring within North Africa 1963-1988 have also been collected and digitized. The regional waveforms of these seismograms have been used to construct 1-D velocity models across several regions of North Africa. We have collected delay time, travel time, focal mechanism, focal depth and magnitude information for these earthquakes. The data bases and results of our studies may be found at the web site httpwww.geo.utep.edunafrnafr.html
