Structurally controlled earth flows of the Benevento province (Southern Italy) (original) (raw)

Abstract

The paper reports an investigation into the distribution and type of landslides in the Benevento province in southern Italy, between 2001 and 2008. Field mapping was undertaken at various scales up to 1:10,000 depending on the features identified. Landslide types were recognized within 5-group litho-technical sequences cropping out in the province, grouped according to their similar mechanical and lithological features. The analysis showed a widespread diffusion of Earth Flows, with reactivation linked to both rainfall and seismic events. They are structurally controlled related to bedding, stratigraphic/tectonic contact between more and less competent sequences and a high degree of tectonisation.

Résumé

L’article présente une recherche sur la répartition et les types de glissements dans la province de Benevento dans l’Italie du Sud entre 2001 et 2008. La cartographie de terrain a été réalisée à diverses échelles jusqu’au 1/10,000 en fonction des caractéristiques identifiées. Les mouvements de terrain ont été identifiés au sein de 5 ensembles lithostratigraphiques présents dans la province, définis sur la base de caractéristiques géomécaniques et lithologiques similaires. L’analyse montre une large répartition des coulées de boue, leur réactivation étant liée à la fois à des événements pluviométriques et sismiques. Elles sont contrôlées par des facteurs structuraux relatifs à la stratification, à des contacts stratigraphiques ou tectoniques entre des unités de compétences différentes et à des forts degrés de tectonisation.
