The purpose of this chapter is to focus attention on the "damage and risk" side of the geohazard (GHZ) phenomena rather than on their generating processes. Damage evaluations are indeed often neglected and oversimplified in predictive studies. As a result, risks are poorly understood and often considered as the mere expression of the …Web
