Drawing on historical documents and a detailed field study, we have been able to characterize the Güevéjar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
