Short summary
Accurate prediction of the relocated position of buildings (and the trapped victims) within debris-flow and landslide deposits is challenging. We elucidate the complicated physical mechanisms associated with the movement of building fragments within debris flows. A set of analytical models considering the physical mechanisms is further established. These findings provide reference for post-disaster emergency rescue by enabling positioning of buried structures.
