Abstract

The A. discuss the results of historical researches about the instabilities those involved, since 1764, the pyroclastic soils covering the Mount Pendolo in the Gragnano area. These phenomena show a significant trend to occur repeatedly in the same places. The influences of the morphologic settlements and the meteorological events are evaluated. In particular, the instability processes are related to continuous rainy sequences (about ten days) with a final peak value above 100 mm. Two threshold values of the cumulative rainfall are defined : the former is about 300 mm and induces more numerous and deeper events. The instabilities are classified as water-sediment flow processes. - (NF)
