Displacements of a likely slab failure were measured, suggesting an apparent stationary stage. Furthermore, the historical record revealed (c) the occurrence of slab failures with magnitudes higher than 150 m3. Two types of mass movement were detected in the monitoring period: (a) detachment of single basaltic columns, with magnitudes below 1.5 m3 and (b) detachment of groups of columns, with magnitudes of 1.5 to 150 m3. rockfalls, was performed through a sequential comparison of datasets. TLS datasets consist of high density 3-D point clouds acquired from five stations, nine times in a time span of 22 months (from March 2006 to January 2008). Rockfall activity is currently causing a retreat of the rock face, which may endanger the houses located at its edge. The pilot study area is an almost vertical, fifty meter high cliff, on top of which the village of Castellfollit de la Roca is located. ![]() This case study deals with a rock face monitoring in urban areas using a Terrestrial Laser Scanner.
