Video: The chronicle of a slow moving landslide; Val Parghera Switzerland

Contrary to the common belief that landslides are violent, quickly evolving natural phenomena, triggered by heavy rain, earthquakes or volcanic activity, today's time lapse proves that landslides may move much slower. The time lapse presents the evolution of a landslide in Switzerland over a time span of 20 months as monitored by a Swiss consulting firm. 

The Val Parghera landslide, at Switzerland's largest canton; Grisons is a slowly evolving phenomenon occurring next to important infrastructure such as railways and highways. To monitor the landslide, GEOPRAEVENT consults, hired by the canton's authorities, installed webcams, radars and laser scans in the area. Engineers measured different landslide velocities ranging from 3.9inches per hour (recorded in June 2013) to as low as 0.4inches per month.
