We investigated the prehistoric earthquakes produced by the Galera Fault (S Spain) during the las 24000 years. We deduced from these analysis the basic parameters that permit to characterize the seismic hazard of this fault. Furthermore, we discuss how the Galera Fault is prone to produce seismic crisis. We also propose that one of these crises could have been responsable for the abandonment of Bronze Age human settlements located near the fault.

This study provides insights into the causes and effects of the largest landslide and related damming that occurred on the emerged Earth surface. Understanding the hazard conditions is important for refining risk mitigation strategies for extreme landslide scenarios. We mapped and dated lacustrine and fluvial terrace sediments constraining the evolutionary model of the valley, thus providing the basis for future studies on the possible seismic trigger for such an extreme case study.

For assessing landslides, it is of particular interest to delineate their volume. For example, numerical models, as well as GIS procedures, rely on exact delineations to characterize hazard potentials. This work presents parameters describing the dimensions and shapes of landslides. Via stable relations among each other and their relations to initial rupture volumes of landslides, it becomes possible to deduce parameters from each other and to infer volume estimates from given parameters.
