In this contribution we present an application of the trajectory simulation tool RockGIS, which explicitly accounts for fragmen-tation, to a recent rockfall event occurred near Vilanova de Banat (Spain). All parameters of the model controlling the kinematics of the propagation and fragmentation have been calibrat-ed in order to reproduce the number of fragments generated and trajectories followed by the blocks. Several performance criteria have been considered and simulations with and without accounting for fragmentation have been performed to assess their influence. The results con-sidering fragmentation show a reasonable matching with the observations in the field.
