A new methodology based on curvature analysis used to map subsidence-related hazard areas in the city of Tuzla (BiH)

Novel methodology to identify areas of localized deformation in a sinking urban area of Tuzla (BiH). Given that the major damage to buildings and infrastructure has been focused in areas of strain localization (surface fractures and faults), we used surface attributes to identify them. The surface attributes used are the directional, gaussian and normal curvatures computed from the cumulative subsidence surface. We compared maps of faults and fractures exposed at the surface to the curvature maps obtained with the previously mentioned methods.
