The knowledge of the Rockfall Block Size Distribution (RBSD) generated by the propagation of the rockfall mass is required for th e analysis of the trajectories o f the blocks, the run - out distances, the impac t energies, the quantitative assessment of the rockfall hazard and for the understanding of the fra g- mentation process . We have measured the volume of the blocks detached in 5 rockfall cases, obtaining the corresponding RBSD. The total volume involved in th ese rockfall events ranges from 2.6 m 3 to 10000 m 3 . The obtained RBS D can be well fitted by power laws with exp o- nents ranging from 0.51 to 1.27. The results suggest that t hese exponents may be related to the height of fall ( potential energy ) and to the pro portion of new fractures generated in the rock mass , among other factors.
