Abstract
The prediction of landslide reactivations in space and time is of relevantpractical interest in the northern Apennines. Dormant or active earth slides-earth flows affect,directly or indirectly, about 1800 villages and many km of road networks. Four test sites havebeen studied and monitored in order to analyse hydro-mechanical conditions in and aroundthe landslides, prior or during reactivation events. Data from monitoring systems such aselectric piezometers, spring and stream discharge flow-meters, inclinometers, Time DomainReflectometry (TDR) cables, Differential Global Positioning System (DGPS) networks andwire extensometers have highlighted some interplay between flow and mass transfers fromstable rock masses to the landslide body, and within the landslide itself. Monitoring in the2004-2006 period has covered dormancy, reactivation and suspension phases, allowing someconsiderations to be drawn on the hydro-mechanical mechanisms that drive the reactivationof large and deep seated landslides.
