Writers at NASA's Scientific Visualization Studio said "Landslides are one of the most dangerous natural hazards on the planet. Between 2007 and 2015, there were more than 25,000 reported deaths due to rainfall-triggered landslides around the world,"
The Aral Sea, once the fourth largest lake in the world is today rapidly shrinking, as a result of the diversion of the two major rivers feeding it, back in the '60s. The effects of the Aral Sea desiccation are widely felt in the local population and the ecosystem, transforming the area in the borders between Kazakhstan and Uzbekistan into a vast toxic desert. Watch the video below with NASA's satellite pictures of the area, showing the water level changes over the years!
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.
