Abstract

The San Vittorino Plain is characterized by the presence of numerous sinkholes, often filled with mineralized spring waters. The development of these sinkholes is mainly due to deep suffusion and deep piping processes, linked to fluid upwelling along fracture-fault systems and to dissolution (by H2S and CO2) in the continental deposits. The sinkhole distribution suggests that they are mainly formed in a collapsed sector of the Mt. Paterno block whose structural setting, characterized by several splays, with marly-clayey and siliciclastic deposits at the footwalls, favoured the development of confined aquifers. The rise of groundwater to the surface along the network of faults and fractures crossing the carbonate bedrock is likely controlled by hydrostatic pore pressures, which may be strongly increased by earthquake shaking. - (NF)
