Seismic microzonation (Aosta Valley – I)

Courmayeur, Pré St. Didier, Valtournenche municipalities

During 2010, in the frame of the Interreg RiskNat Project, the Aosta Valley decided to undertake the first pilot studies on seismic microzonation, selecting three main municipalities: Courmayeur, Pré Saint Didier e Valtournenche.
As prescribed by the Civil Protection guidelines, the main task of the study was the assessment of local seismic hazard through the identification of zones with seismically homogeneous behaviour. In practice, stable zones, stable zones prone to local amplification of seismic movement and zones prone to instability were identified.
