Abstract

In Part I a review of the experimental and theoretical research on the effects of surface topography on earthquake ground motion done in the last 20 years reveals significant disagreements between observations of the ground motion on top of elevated topographies, like mountain ranges and hill, and the corresponding theoretical predictions.  

In Part II several examples of modelling the effects of two- and three-dimensional generic topographies on the ground motion due to earthquakes are presented and discussed.
