These structures are created by unforeseen events and appear on the surface by collapsing. Carbonate rocks, sensitive karst dissolution, depend on the instability of the geodynamic process which continues to the soil surface. In the case of presence of the sinkhole, it is important to delineate risk areas in order to define a perimeter of protection for the water resource and geotechnical work. In this objective a collapse takes place in February 2015 at El Ouldja (North-East of Algeria), a geophysical surveys, including 2D electrical resistivity imaging and electromagnetic induction method (EM31), were employed in the early stages after the initial collapse to determine the risk areas and collapsed features in depth. The work took place on April 2015.
