Video: Immense hole appears in Siberia and prompts expedition

The earth abounds with sinkholes caused for different reasons from mining to shifts in the crust. This new one in Siberia may have been caused by something entirely new.

Teams have already been dispatched from the Centre for the Study of the Arctic and the Cryosphere Institute of the Russian Academy of Sciences. According to a report from the Siberian Times they will be taking samples from the site and studying them for clues as to what caused this.
Giant holes such as this one are not entirely uncommon. What is surprising is that one of this size appeared so suddenly. In any case it's an intriguing find for geologists. Scientists are already studying massive holes in Antarctica and other areas to better understand how our planet works.
Another question scientists will have to cope with is how to deal with the vicious cold in Siberia. The area has an average temperature of −5 °C (23 °F) which is impossible to survive in without proper shelter and equipment.
Scientists know a few of the factors that cause sinkholes but still do not fully understand all the circumstances they occur under. This new event should give the scientific world some new insights into their nature.
