• Assessing the travel distance of rockfalls requires the appropriate characterisation of the factors that govern instability processes. These factors can be divided into those governed by the source area, those related to the trajectory, and other extrinsic factors like the weather conditions. In this paper, methodology is proposed that aims to identify the above mentioned factors by means of field and geomorphological techniques. The characterisation of the source area and the location of future rock falls have been specifically discussed. Simulation programs have been used to determine rockfall travel distance, in order to plan mitigation measures. The chosen study area is Merilla-Ajanedo, located at the intersection of two distinct tectonic features in Cantabria: the "Escudo Thrusting Front" and the "Selaya-Arredondo Fault"
