Fear of hell on Earth as huge mysterious hole appeared in Siberia

Russia: Researchers in Russia are investigating a giant mysterious hole that has appeared in one of Russia's most isolated northernmost regions.

It is still unclear what may have caused the huge crater, about 100 meters in diameter, filmed from the air in Yamal, which means 'the end of the Earth' in the local Nenets language. The area is known to have temperatures plummet to -50 degrees Celcius and the sun barely rises in winter.

Plans to collect soil and water samples from the site was planned with  researchers from the Siberian nad Russia leading the expedition

There are reports that the hole appeared to have been caused from below and that the darker soil around its top indicated the effect of high temperatures, due to an underground explosion.
