Unravelling the multiphase run-out conditions of a slide-flow mass movement

A reactivation of the mass movement by frictional sliding of the material half way the run-out track was simulated. It occurred 30 min after the first run-out phase due to an increase in pore pressure. The sliding material changed into a slow flowing mass that reached a newly built up area after about 1 h and moved into Wangong Town over a distance of 80 m.
