Brief communication: Accuracy of the fallen blocks volume-frequency law
Valerio De Biagi Department of Structural, Geotechnical and Building Engineering, Politecnico di Torino, Torino, Italy
Abstract. De Biagi et al. (2017) have proposed a procedure for building a fallen block volume-frequency law for rockfall phenomenon. The input data are got both from the recording of rockfall events and from the survey of fallen block volumes. The epistemic uncertainty present in the approach affects the value of the parameters of the law. It is shown how to quantify the error due to missed events and to limited set of measured blocks. A procedure for getting a rock block volume for the design of engineering applications is proposed.

Short summary
Some interesting questions raised during the review process of a recent paper on a method for obtaining a fallen blocks volume-frequency law, e.g., related to the minimum number of observations needed for obtaining the law. This brief communication addresses this point. In detail, the errors due to a reduced number of recorded fallen block events and to the consistency of the measured blocks at the foot of the cliff are computed. This is useful for design purposes.
