Tsunami Vulnerability Evaluation for a Small Ancient Village on Eastern Sicily Coast

The Ionian sea is prone to tsunamis due its proximity the Calabrian subduction zone, which one of major tsunamigenic areas Mediterranean. tsunami disaster risk is, nowadays, significantly higher increased exposure buildings as a result economic and touristic growth Mediterranean coastal areas. This study focuses on Marzamemi, small village in western coast Sicily, since morphology human presence amplify need assess buildings’ vulnerability. main objective this research quantify building vulnerability hazards using physical realistic scenario. For purpose, relative index Marzamemi was calculated by means an improved Papathoma Tsunami Vulnerability Assessment (PTVA) model. presented approach has three improvements: (a) probabilistic scenario used; (b) signal water surface linked with specific focal mechanism adopted; (c) wave propagated from offshore nearshore nonlinear numerical good results proposed methodology make it very useful for planning conducted decision makers stakeholders.
