Brief communication"Estimating rockfall frequency in a mountain limestone cliff using terrestrial laser scanner"

A. Guerin, D. Hantz, J.-P. Rossetti, and M. Jaboyedoff

Abstract. Using terrestrial laser scanner, 344 rockfalls larger than 0.05 m3 have been detected for a period of 1180 days, in a thinly bedded limestone cliff of width 750 m and height 200 m. The complementary cumulative distribution of the rockfall volume is well fitted by a power law, with an exponent b of 0.75 ± 0.04. In order to compare the rockfall frequencies in different geological contexts, a rockfall activity parameter has been defined, which is the number of rockfalls larger than 1 m3, which occur per century and per hm2.
