Extended Data Fig. 2: Definition and calculation of conditional probability of a rock impacting a tree on a slope.
From: Rockfall from an increasingly unstable mountain slope driven by climate warming
(a) The Conditional Impact Probability (CIP)27,61 considers the distribution of trees within a given plot. (b). Computation of impact circles. 1. Tree stem; 2. Circle of impact; 3. Projection of the circles of impacts to the bottom boundary of the cell analyzed; 4. Rock of a given diameter; 5. Trajectory of the falling rock; 6. Rockfall impact. L1, L2, L3 and L4 are the widths of the projection of the circles of impact at the bottom of the cell. LIC is the width of the analyzed cell. Adapted from Ref. 62.
