This sliding movement is too recent (January in 1881) and hit the old town of Puigcercós (Tremp, Lleida), now abandoned. It is an excellent example of moving mass-transfer complex with rotation and flow. Worth noting its dimensions, and the excellent level of preservation of the typical forms (scar coronation to 200 m, rotating platform and frontal lobe). It is a magnificent example to illustrate how the concepts of hazard, vulnerability and geological risk.

The hills of Barcelona are located between the Quaternary littoral plain, where the old part of the city was settled, and the Collserola range. In the hills, a succession of Paleozoic rocks affected by a number of tectonic episodes is preserved (Variscan orogeny, Mesozoic extension, Paleogene compression and Neogene extension). The small size of the mappable units is a scientific challenge. Some of the best outcrops are in Park Güell, a good reason for that geologists visited the work of the famous architect Antoni Gaudí.

The "core" of the massif of Montserrat is constituted by around 1000 m of massive conglomerates. This imposing mass rudites corresponds to the proximal facies of a coastal alluvial fan that flows into the Ebro Basin during the Eocene. Three It should be noted aspects:

1. It is a paradigmatic example in the world that allows fine depositional sequences in an alluvial fan.
2. On a geomorphological feature the impressive forms (monoliths, cliffs...).
3. It is a place of special historical significance, cultural and spiritual in Catalonia.
