Short summary

The influence of meteorological conditions on rockfall occurrence has been often highlighted, but quantitative analyses are rare. A near-continuous survey of a limestone cliff has shown that the rockfall frequency can be multiplied by 7 during freeze-thaw episodes and 26 when the mean rainfall intensity (since the beginning of the rainfall episode) is higher than 5 mm h⁻¹. Based on these results, a three-level scale has been proposed for predicting the temporal variations of rockfall frequency.
