Kinematic evolution and shear strength in the complex landslides of the Maratea valley (PZ, Italy)

Abstract

It is suggested that a structural kinematic mechanism could have formed the so-called Maratea “Sackung” (A. GUERRICCHIO, G. MELIDORO, 1979) (more comprehensible as the “Sagging” phenomenon) and enabled the complex surrounding landslides to take place.

For the same deformation speed, the change in resistance as a function of different stress conditions was identified by means of triaxial testing carried out on test pieces obtained from both undisturbed and remoulded samples of the basal clay complex with “Sicilide” affinity.

Finally, the results obtained were compared with slide velocity during the last decade and the various thicknesses of the partially detrital mass in which the main landslides occur.
