Geoelectric Tomography Carried Out on a Mass Movement Site of Kulcs Settlement (in Hungary)

Intensification of the surface mass movement processes on the right bank of the Danube river on the territory of village Kulcs caused serious damages during the past decade. Several significant rehabilitation projects have been performed in order to stabilize the area and protect the settlement. Following the last greater movement, the area of Hullám and Deák Ferenc Streets was declared to Life Hazard Zone. Experimental geophysical measurements along profiles were carried out on areas classified as Life Hazard Zone, in order to explore the possible geological causes of the mass movements. It was investigated if those – probably 2D or 3D – structures which may give explanation to the specific spatial distribution of the surface mass movements could be detected by geoelectrical methods. Multielectrodal direct current method was applied to image the subsurface electrical resistivity distribution. Any given formations identified on the obtained resistivity distributions can be corresponded to a rock type based on prior geological information. The applied geophysical methods contribute to our better understanding of the geological environment of the high bank, provide additional explanation to the causes of the mass movements, and may yield information concerning the place of potential future mass movements. Results may also help us plan further drillings on appropriate sites, and the necessary geotechnical procedures.
