The clays involved in the 1963 Vajont landslide: Genesis and geomechanical implications

Engineering Geology, 2021, 106376, ISSN 0013-7952

Abstract
"...In this work, we investigate the geological origin and provenance of the Vajont clays according to the results of mineralogical and geochemical analyses performed on several clay samples which were collected from the landslide failure surface and the same limestone sequence in the surrounding area.

...During the 1963 remobilisation, the clay layers contributed to the average shear strength decrease of the debris material forming the basal shear zone of the slide, but the main triggering factor was the increase in pore pressures caused by the reservoir-induced groundwater inflow".
