The need for the development of PyrMove lies in the almost total absence of data on risks associated with landslides in the Pyrenees.

Recent studies show that landslide census work is much lower in the Pyrenees than in other large mountain ranges in Europe (Van Den Eeckhaut and Hervás, 2012). Therefore, it is extremely important to start a systematic census of landslides in this region, understand the mechanisms that control them, and assess the associated potential risks. This exercise will allow transferring to the Pyrenees a large number of results existing in other areas on the identification of unstable areas, the evaluation of the frequency of the landslide phenomenon, its relationship with rainfall and the development of methods to reduce  associated risks.
