Fig. 7 Relief vs slope angle at 284 rockfall scars (see Fig. 1 for locations). Square and circle points represent data from left- (L)and right-hand (R) valley flanks. DL and DR (km) are the distances from fault core. CL and CR (kPa) are estimated cohesion values of bedrocks. C-A (to F) represent the 7 clusters (A to F) of rockfall scars in Fig. 1.
