Human-induced hazardous debris flows in Carrara marble basins (Tuscany, Italy)
In Carrara marble basins, the long and intensive quarrying activities have produced extensive dump deposits, locally known as ravaneti. The morphological and sedimentological analyses of depositional lobes resulted in a classification of 3 types
of lobe, based on fabric-morphometry relationships allowing the identification of different flow dynamics. In Carrara marble basins, the anomalous frequency with which debris flows tend to be triggered by medium-intensity rainstorms is due to the recent
