Study shows that the 'Gateway to the Underworld' in Siberia is getting bigger every year

 

Siberia in Russia is an extremely cold region. An area that has been under ice for centuries. But in recent times the snowmelt in the region has been strong. The 'gateway to the underworld' is a large crater formed in the area where the snow has melted. Studies have shown that this threshold is larger than expected every year. Considered to be one of the world's largest craters, new studies show that it is growing by 35 million cubic feet each year. The study also points out that the large crater, located in the permafrost of Serbia, is expanding as the region's ice melts. Permafrost refers to areas that have been permanently covered by snow or water for many years.
