Short summary
Large earthquakes trigger thousands of landslides in the area of their epicentre. For three earthquake cases, we have determined the position of these landslides along hillslopes. These co-seismic landslides tend to cluster at ridge crests and slope toes. We show that crest clustering is specific to seismic triggering. But although co-seismic landslides locate higher in the landscape than rainfall-induced landslides, geological features strongly modulate their position along the hillslopes.
