Forthcoming climate changes, recognized by the international scientific community, are inducing a modification of the hydrological cycles with a direct impact on the piezometric regime of natural slopes and thus on their stability conditions. Particularly regarding active landslides in fine grained soils, the experience based on several well documented cases suggests an evident connection between landslide activity and rainfalls cumulated over some months. As a consequence, the observed change of the rainfall features should provoke variations on the kinematic features of such phenomena. Its role could be not negligible in a landslide risk assessment.Thanks to the availability of a considerable database related to the well documented Orvieto case, regarding precipitations and displacements of an active slide in clay, monitored since 1982, and to a climate projection occurring in the concerned area, provided by a reliable Regional Climate Model, the present paper gives a likely prediction of the long-term scenario of the landslide behavior. According to our results, local climate effects should be responsible of a slow decrease in the displacement rate
The Central Italy earthquake sequence nominally began on 24 August 2016 with a M 6.1 event on a normal fault that produced devastating effects in the town of Amatrice and several nearby villages and hamlets. A major international response was undertaken to record the effects of this disaster, including surface faulting, ground motions, landslides, and damage patterns to structures. This work targeted the development of high‐value case histories useful to future research. Subsequent events in October 2016 exacerbated the damage in previously affected areas and caused damage to new areas in the north, particularly the relatively large town of Norcia. Additional reconnaissance after a M 6.5 event on 30 October 2016 documented and mapped several large landslide features and increased damage states for structures in villages and hamlets throughout the region. This paper provides an overview of the reconnaissance activities undertaken to document and map these and other effects, and highlights valuable lessons learned regarding faulting and ground motions, engineering effects, and emergency response to this disaster.
