Google Earth timelapse shows amazing imagery of what happened before and after several landslides in Oso, WA. The river experiences a large build up of sediment upstream while downstream the river does not get as sediment choked. The landslide dams the river causing an increase in slope upstream, increasing basal shear stress, causing more sediment to flushed downstream towards the landslide dam. Eventually, the dam is breached.
