abstract = {The urban area of Albuñuelas, a small town located to the south of Granada (S Spain),
has been developed in terrain affected by a large-scale rotational landslide with very slow rate of
movement. Despite this situation, the internal structure of the landslide and how it has evolved to
its present state has not been analyzed in depth up to now. In this paper, we present the first study
performed on this landslide to define its configuration and characteristics. For this purpose, ambient
noise single-station and array measurements were carried out along several cross-sections of the
landslide. The inversion of the measurements has allowed for the estimation of the soil stratigraphy
at each site of measurement. These geophysical results have been constrained by data from a borehole
drilled in the zone and from field observations of the local geology, allowing for the reduction in
uncertainties in the results. A geological–geophysical model of the landslide has been built from
these data, showing that the landslide thicknesses is greater than 50 m in its central parts and above
60 m in the upper ones. This model reveals that the evolution of the landslide was complex, with
several dislodged elements (blocks) that moved in sequence (retrogression) and were partially eroded
in order to explain present morphology. The future evolution of this landslide will be controlled by
the composition of the materials surveyed along the foot of the valley, being the western part where
there are more erodible materials according to the obtained results.},
