We analyze the problem of a heterogeneous formulation of the equation of motion and
propose a new 3D fourth-order staggered-grid finite-difference (FD) scheme for modeling …

Despite the ever increasing adoption of wave motion simulations for assessing seismic
hazard, most assessment/simulations are still based on a flat surface earth model. The …

In this paper, a half-plane time-domain boundary element method (BEM) was presented for
analysing the 2-D scalar wave problems in a homogenous isotropic linear elastic medium …

The interaction of seismic waves with slopes is a major factor influencing landslide
movements that involve slope stability, local site seismic amplification and topographic …

Hundreds of landslides were triggered by the mainshocks (up to Mw 6.5) that occurred in
2016 in Central Italy during the seismic sequence that originated in the Apennine and ended …

This paper presents the results of a numerical parametric study on the seismic behaviour of
3-D Gaussian-shaped valleys subjected to vertically propagating incident waves. The …

This paper extends a method, which has been previously called half-plane time-domain
boundary element method (BEM) and successfully applied to 2-D concave topographies, for …

The study regards an evaluation of site effects on and near the Monte Po hill, located in the
north-eastern part of the city of Catania (Italy), an area at high seismic risk. At the beginning …

This paper deals with the evaluation of two-dimensional site-effects due to the seismic
interaction between hills with various configurations and underground cavities. The time …

In this paper, normalized displacement amplitude of the ground surface was presented in
the presence of the semi-sine shaped valley above the truncated circular cavity embedded …
