El Deslizamiento de Güevéjar (provincia de Granada): un caso de inestabilidad de laderas inducida por sismos

Abstract

Drawing on historical documents and a detailed field study, we have been able to characterize the Güevéjar landslide as a complex landmass movement with a dominant multi-rotational component. The landslide body is made up of very heterogeneous rocks, while the basal surface is located on lignite-bearing marls. The main triggering factor responsible for this landslide is thought to be the dynamic effect of high magnitude earthquakes with the focus located at very long distances (tens to hundreds of km) from Güevéjar. Some pieces of evidence point to local-scale amplification of seismic waves (site effect) as causing reactivation of the landslide
