| Zusammenfassung |
| Shear wave velocities have a fundamental role in connection with the
mitigation of seismic hazards, as their low values are the main causes of
site amplification phenomena and can significantly influence the
susceptibility of a territory to seismic-induced landslides. The shear wave
velocity (Vs) and modulus (G) of each lithological unit are influenced by factors
such as the degree of fracturing and faulting, the porosity, the clay amount
and the precipitation, with the latter two influencing the unit water
content. In this paper we discuss how these factors can affect the Vs
values and report the results of different analyses that quantify the
reduction in the rock Vs and shear modulus values connected to the
presence of clay and water. We also show that significant results in
assessing seismic-induced slope failure susceptibility for land planning
targets could be achieved through a careful evaluation, based only on
literature studies, of the geo-lithological and geo-seismic features of the
study area. |
