摘要: Susceptibility of intrusion-related landslides in an active volcano was evaluated coupling the landslide susceptibility estimation by random forest (RF), and probabilistic volcanic vent opening distribution, as proxy for magma injection, using QVAST tool. In order to develop test method proposed here, RF/QVAST approach adopted Stromboli (Southern Italy) since it experienced moderate huge instability events, is geomorphologically prone affected intense activity that can produce slope instability. The main destabilizing factors flanks are slope, aspect, terrain roughness, land cover litho-technical features outcropping rocks. Estimation shows areas with high probability new located north-western unstable flank (Sciara del Fuoco), summit north-eastern coherent possible re-activation eruptive fissures related regional tectonic setting. higher upper part Sciara Fuoco, while rest island show low occurrence.
