AB: Coincident seismic and magnetotelluric data, collected as part of the international DESERT (DEad SEa Rift Transect) project, have provided high-resolution velocity and resistivity images of the upper-crustal structure of the Dead Sea Transform. While changes in velocity or resistivity may signal geologic, tectonic, or hydrologic boundaries, looking at these properties in tandem allows for more precise resolution of such boundaries. A combined statistical analysis of the DESERT resistivity and velocity models will be presented. Data from both local and regional profiles exhibit a strong correlation between velocity and resistivity. Cluster analysis can be further used to 'map' out regions of uniform physical properties, and the borders between these regions are often sharply defined. Preliminary results suggest the Dead Sea Transform forms a sharp vertical boundary within the upper 5 km of the crust.
