This Timelapse Captures The Progress Of An Agonizingly Slow Rockslide

There's a rather dramatic landslide in progress in Val Parghera, Switzerland, but you wouldn't necessarily know it by just looking at it. Thankfully, there's now a stop-motion video showing its movements over the past 21 months.


In the video, you can see the movements of the rockslide between May 2013 and January 2015.

Writing in the AGU's Landslide Blog, Dave Petley of the University of East Anglia explains the significance of the video:

First, when viewed at this speed it becomes clear that the behaviour of the Val Parghera landslide is very much like a fluid flow, even to the extent of seeing higher velocities in the lower, narrow part of the landslide. Second, there is a very complex coupling between the main body of the landslide and this lower portion. At times it appears that the lower part slides first, removing the support for the main body of the landslide, whilst at others it seems that the main portion moves, loading the lower part of the slope.


He also points out that the most impressive movement happens at the end of March 2014, which is likely on account of it being at the end of winter.

Awesome. Can we have the video of paint drying next?
