摘要

This paper proposes an overview on ancient earth flows of the Emilia-Romagna Apennines and their reactivation mechanisms, with a view to gleaning information that can subsequently be utilised to formulate a risk reduction strategy. All considerations made herein are the result of direct experience and observation of actual events which have occurred over the past few decades in the Northern Apennines. Particular attention has been paid to the analysis of the evolution of landslides during actual reactivation, acknowledging a typical, recurring succession of events that precede the failure of the slope. The hazard assessment of these large landslide bodies, which are of slope scale, constitutes a thorny problem, especially in view of the inapplicability of traditional deterministic models such as limit equilibrium stability analysis. The usual set of factors that form the basis of deterministic methods is insufficient to make reliable predictions about the future behaviour of these landslides and their related hazard. Nevertheless, a site-specific assessment of probability of reactivation is fundamental to effective land-use planning. In general, the observation of past events has proved to be a useful mean for understanding which are the conditions and behaviours that usually lead to the reactivation of an ancient landslide body.
