An urgent expedition will leaves tomorrow to probe a giant crater that has appeared in gas-rich northern Siberia.
Extraordinary aerial images show a mysterious hole which experts say may be up to 262 feet wide, in the Yamal Peninsula of northern Russia.
‘A scientific team has been sent to investigate the hole and is due to arrive at the scene on Wednesday,’ The Siberian Times has reported.
The cause of the hole’s sudden appearance in Yamal – which translates as ‘the end of the world’ – in the far north of Siberia is not yet known.
There has been web speculation about the crater indicating ‘the arrival of a UFO craft’.
But one Russian expert says the cause is more likely to be global warming releasing gases under the surface, which then explode like a champagne cork.
