Abstract. The rock avalanche that destroyed the village of Xinmo in Sichuan, China, on 24 June 2017, brought the issue of landslide risk and disaster chain management in highly seismic regions back into the spotlight. The long-term post-seismic behaviour of mountain slopes is complex and hardly predictable. Nevertheless, the integrated use of field monitoring, remote sensing and real-time predictive modelling can help to set up effective early warning systems, provide timely alarms, optimize rescue operations, and perform secondary hazard assessments. We believe that a comprehensive discussion on post-seismic slope stability and on its implications for policy makers can no longer be postponed.

Short summary
The long-term effect of strong earthquakes on geological hazards in mountainous areas is an underestimated issue, but the integrated use of field monitoring, remote sensing, and real-time predictive modelling can help to set up effective early warning systems, provide timely alarms, optimize rescue operations, and perform more accurate secondary hazard assessments. With this paper we wish to stimulate an open discussion on post-seismic slope stability and its implications for policy makers.
