Short summary

Large earthquakes commonly trigger widespread and destructive landsliding. This paper tests the hypothesis that spatial distributions of earthquake-induced landslides are determined by both the conditions at the time of the triggering earthquake and the legacy of past events. Our findings emphasise that a lack of understanding of the legacy of damage in hillslopes potentially represents an important source of uncertainty when assessing regional landslide susceptibility.
