The 1963 Vajont Slide was an unparalleled natural disaster; it produced a displacement wave that overtopped the Vajont Dam and destroyed several villages, with the loss of over 2000 lives.

Abstract
The 1963 Vajont Slide was an unparalleled natural disaster; it produced a displacement wave that overtopped the Vajont Dam and destroyed several villages, with the loss of over 2000 lives. In the aftermath of this catastrophe, numerous researchers have attempted to understand the mechanisms and behaviour of the landslide. This paper presents the results of the first detailed digital photogrammetric survey of the Vajont failure surface. Discontinuity orientations were detected and eight discontinuity sets were characterised. Surface morphology profiles reveal several scales of roughness and folding, from a regional-scale syncline to small-scale roughness, all of which played a significant role in failure behaviour.I documenti in SFERA sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
