Short summary
Rockfall is an highly destructive and unpredictable natural phenomenon. The design of protective structures needs a design falling block. Nowadays, the size of this block depends on the designer's personal judgement and expertise. We propose a statistical methodology to evaluate the return period of a given falling volume from observations and records in historical catalogues. This would allow us to implement modern reliability-based design approaches in protective engineering works.
