The landslide masses flow down along the terrain. Quick clay landslides are of two main types – stepwise and uninterrupted. In stepwise landslides, sufficient failed material liquefies that the debris from each step flows away from the slide scarp, leaving an unsupported unstable slope that, in turn, fails and flows away. The deadliest quick clay landslide in Norway’s history occurred on May 19, 1893, in Verdal, Trøndelag county.
