Abstract

Le 7 mars 2005, après qu'une période des précipitations extraordinaires (645 millimètres dans 90 jours, environ 72% de précipitation annuelle moyenne) combiné avec des chutes de neige, Cavallerizzo a été sévèrement endommagé par une vaste l'éboulement complexe de terrain. 30 édifices ont été sévèrement endommagés par l'éboulement et la route reliant le village de Cavallerizzo aux communes voisines a été interrompue. Environ 310 habitants ont dû être logé dans les villages voisins. Plusieurs unités tectoniques superposées, faites de roches métamorphiques (Palaeozoic-Mésozoïques) et terrains clastiques de recouvrement (Cénozoïques-Neozoic) sont les lithologies qui affleurent dans la zone. L'escarpement principal du glissement s'est développé le long une ligne tectonique localisée a Ouest de la Chaîne Côtière, délimité par la récent faille normal \"San Fili-Cerzeto-San Marco Argentano\", orientée NS et vraisemblablement active. Le secteur de couronne est situé dans la zone cataclastique liée à la ligne tectonique mentionné ci-dessus. Dans la partie plus inférieure de l'éboulement, deux principaux corps de coulées se prolongent vers l'Est le long des drainages secondaires, réunissant ensemble le long du torrent S. Nicola. Le secteur affecté appartient à un mouvement de terrain de grande ampleur, qui se prolonge à l'Ouest jusqu'à la ligne de partage des eaux. L'événement 2005 est le dernier d'une histoire de déformations qui se développe depuis le siècle XVIII. Le secteur a été occasionnellement contrôlé par le CNR-IRPI au moyen de mesures sur le terrain (déplacements profonde et superficielles et niveaux piézométriques) depuis 1999. Les vitesses de déplacement, enregistrées aux repères superficiels situés le long des fissures d'ouverture, ont précisé des conditions \"anormales\" pendant les semaines précédant l'éboulement: les vitesses de pré rupture se sont étendues de 0.8 à 5-6 cm/jour. En dépit de son caractère simplifié, la surveillance a aidé dans les activités de protection civile et a permis de sauver tous les habitants (literal)
In the early morning of March 7th 2005, after a period of prolonged rainfall (645 mm in 90 days, about 72% of mean annual precipitation) and snowfall, the hamlet of Cavallerizzo was severely damaged by a vast complex debris slide-earth flow. In total, thirty buildings were severely damaged or destroyed by the landslide, and the main road connecting Cavallerizzo with the villages of Cerzeto and Mongrassano was disrupted. About 310 inhabitants had to be evacuated to nearby villages. Several superimposed tectonic units, made of metamorphic rocks (Palaeozoic-Mesozoic) overlain by clastic terrains (Cenozoic-Neozoic), crop out in the vicinity of the study area. The main scarp of the slide developed at the eastern tectonic boundary of the Coastal Chain, marked by the \"San Fili-Cerzeto-San Marco Argentano\" recent (presumably active) N-S trending normal fault; its crown is mainly located within the cataclastic zone associated with such master fault. In the lower part of the landslide, two main earth-flows extended eastward along minor valleys, that merged down slope along the S. Nicola torrent. The sector affected by the landslide belongs to a wider large-scale slope movement, which extends westwards up to about 800 m a.s.l. The 2005 event is only the last paroxysmal episode of a long history of deformation recorded in the area of Cavallerizzo since the XVIII century. The area has been kept under control by the CNR-IRPI, by means of desultory field measurements (essentially, deep and superficial displacements, and piezometric levels) since 1999. Velocities, recorded at superficial benchmarks along opening cracks, pointed out \"anomalous\" conditions in the weeks preceding the collapse: pre-rupture velocities ranged from 0.8 to 5-6 cm/day. Despite its emergency character, the monitoring carried out helped to support civil-protection activities, and allowed all inhabitants to be saved. (literal)
