ABSTRACT
Since the early work of Heim (1932) and Terzaghi (1950), landslide researchers have striven to better understand and predict catastrophic slope failure. Despite considerable advances in understanding landslide mechanisms and being able to simulate them using numerical models, prediction of the onset of extremely rapid motion and the resulting propagation (runout) of the slide mass is still exceedingly difficult. This paper attempts to list and critically review the main existing techniques and quantitative models. Given the explosion of literature dealing with this subject in recent years, our treatment is necessarily selective.
