Abstract

Italy is characterized by frequent and widespread phenomena of

geological instability and floods. The main factors that

geological and hydraulic risk are the geomorphologic

Italian territory, characterized by a relatively young environment often

still in evolution. These specific dynamics and phenomena are frequently

triggered by heavy rainfall like the one happened last 1st October in

Giampilieri (ME) where more than 30 people w
