Last November, a giant crater had emerged after the collapse of a potash mine in western Russia.
9 months later, it has grown so big – from 120 ft to now 400ft – that it has became a threat for surroundings homes and forest.
The large crater has been continuously growing since it first appeared near the town of Solikamsk in the Perm region.
From initial dimensions of 30 by 40 meters (100ft by 120ft), the crater has expanded to amazing 122 by 125 meters (400ft by 410ft).
And if you look at the images, you clearly see that the hole near Solikamsk is gently but surely swallowing the entire town and surrounding forest.
Currently the hole has a depth of 75 meters and can even be seen from space.
The Solikamsk potash mine has promised compensations for homeowners. Moreover, it has started the hydraulic filling of the old mines in order to reduce the deformation of the rock mass.
