Huge Landslide Destroys Houses in Norway

137

This video shows the scary moment a huge landslide took entire houses to waste. Denizens were doing their daily activities when they heard loud creaking. Soon after they saw power lines going down and felt the ground moving.

Luckily, they ran away on time and nobody was injured. These were mostly cottages and holiday houses which were insured. One dog was caught in the landslide, but it was rescued with a helicopter.

Norwegian authorities determined that the cause for the slide was a layer of quick clay. This unstable clay is a common cause for landslides in northern countries such as Canada, Norway, Russia, etc. Depending on the conditions, the material behavior may drastically change from that of particulate material to that of watery fluid. This is caused by its highly unstable clay particle structure.
