“…Though my results demonstrated gentle slopes to be more prone to sinkholes, Stecchi et al (2009) reported building destruction initiated by ground subsidence on these "gentle" slopes. It is interesting to define the thresholds of "gentle" and "steep" slopes; from this study, it is clear that slope boundaries are highly subjective, even on the small-scale, local analysis that this study is built on.…”

“…The 'identity' tool further enabled the partnering of each point with its related topographical slope, curvature and altitude values, and enabled the integration of statistical testing and GIS. Curvature can be defined as the degree to which a surface is curved, and can be strongly linked with trends of faults and topographical fractures (Stecchi et al, 2007). The curvature is the second derivative of the elevation surface, which was run on a 3x3 cell scale determined by the DEM grid size resolution.…”

“…Though zonation maps have been previously created, they have been predominantly single-site based and scale-specific (Kaufmann and Quinif, 2002;Stecchi et al, 2009). This paper aims to further this research by creating a comparative map of two areas based upon multiple surficial factors.…”

“…Slope, altitude and curvature each presented a difference with Kruskal-Wallis testing and a further post-hoc Mann-Whitney U for individual bedrock class pairing. The results were more varied for Malham, with less of a pattern presented; limestone consistently to remove any minor topographical hollows or peaks (Sullivan et al, 2007;Stecchi et al, 2009). Each surficial factor was reclassified into low-high susceptibility groups based on natural breaks, which was used to highlight the values where points naturally clustered.…”

“…These predominantly focused on preexisting cavities, where the limestone cave systems that were once mining sites, initiated subsidence. Recent literature now focuses more upon the range of external factors that exert pressure on these vulnerable locations, due to the increasing availability of modern technological equipment, allowing more in-depth analysis (Sass, 2007;Stecchi et al, 2009). …”

Ground deformation phenomena affecting the town of Tuzla (Bosnia Herzegovina), as consequence of underground salt deposits exploitation, have been surveyed since 60 years ago. The growing of cavities beneath the town and successive surface deformations have induced several hazard factors such as ground subsidence, deep and\ud shallow fracturing and intense groundwater table oscillations. Fortunately, this processes had no catastrophic consequences such as sinkholes developing. Previous studies analyzed\ud the historical database of topographic and piezometric data and highlighted a cumulative subsidence rate up to 12 meters over a period spanning from the 1956 to the 2003. Fractures arose as obvious result of ground deformation and caused damages and demolitions to thousands of buildings, with almost 15,000 people evacuated. Nowadays, in order to diminish the deformation processes, a strong reduction in brine withdrawal has been introduced by the local authorities. This caused an uplift of the water table which actually makes the spatial pattern of deformation more complex. In fact, in the most urbanized area, the sinking phenomena are now turning into uplift displacements. The presence of such a hazard required an urban vulnerability assessment able to support local authorities in the forthcoming planning procedure. The vulnerability assessment of urban elements over a wide area, potentially affected by deformation phenomena, has been accomplished by an integration between GIS solutions and a multicriteria approach based on ELECTRE-TRI methodology. The vulnerability procedure is able to define a discrete map where the 50 9 50 m width elementary cells report the most vulnerable parts of the town. In particular, the ELECTRE-TRI methodology is used to combine each vulnerable urban element with the others, expressed as vector data in a geographical dataset. The multicriteria approach is performed outside the GIS environment by the ELECTRE-TRI 2.0 package and requires a preliminary rasterization of the used dataset
