Collapse sinkholes in the carbonate massifs of Central and Southern Apennines (original) (raw)

This study focuses on karst collapse sink�oles of t�e sout�ern and central Apennines region (Italy), and �as t�e aim of outlining and discussing t�e factors w�ic� contribute to t�e occurrence of collapse p�enomena. By t�e analysis of t�e mor-p�ometrical/morp�ological features of t�e about 600 initially identified sink�oles, about 50% were interpreted as collapse sink�oles related to karst p�enomena, w�ic� are t�e object of t�is study. These were geo-referred and organised in a data base, in w�ic� information on t�e geological-structural and �ydrogeological features of areas affected by t�e collapses was also reported. The collapse sink�ole inventory was paralleled by an analysis of t�e distribution of t�e main mineral springs (H 2 S-and CO 2 -ric� waters), of travertine bodies and of extensional faults wit� late quaternary activity, w�ic� were all considered significant to t�e study due to t�e interrelations linking travertines, karst solution processes, CO 2 -ric� waters and faults. Furt�ermore, wit� t�e aim of investigating t�e role of seismic s�aking in t�e occurrence of t�e collapses, t�e karst collapse sink�ole distribution was compared wit� t�e distribution of stronger �istorical eart�quake epicentres. The results of t�is regional scale synt�esis suggests a possible key to t�e interpretation of karst collapse p�enomena. The latter, in fact, appear correlated to t�e combination of peculiar conditions, w�ic� may be envisaged in t�e presence of active faults and mineral waters. The study, in particular, suggests t�at karst collapse sink�oles result from en�anced dissolution p�enomena related to t�e rising of fluids of deep origin, for w�ic� active
