A sinkhole in Russia has tripled in size in the past ten months - resulting in a 120 metre wide crater.
The hole, which has swallowed up to 20 local weekend cottages, is even visible from space and is believed to be more than 75m deep.
The chasm, located near Solikamsk in the Ural Mountains, first appeared after the collapse of a former potash mine at the end of 2014.

According to a report in the Siberian Times, it began caving in at the end of 2014 with measurements of a modest 20 x 30m.
Now ranging at 120m in width, the still-expanding hole is threatening nearby holiday homes and forest.
The crater is close to the Solikamsk-2 mine owned by the world's number one potash producer, Uralkali.
The sinkhole appeared around the same time as mass flooding at the mine in November last year.
Last month a sinkhole opened on a main road in Manchester which was thought to be 40ft wide and 30ft deep.
Weeks later another chasm appeared, at about 10ft deep and 5ft wide it measured much smaller in size.
