A Journey Into A Mysterious Siberian Crater
Three massive craters were discovered this summer on the Yamal Peninsula in northern Siberia. In an effort to understand the origins of the newly formed craters, a group of scientists descended into one of the holes, reaching a frozen lake at the bottom. Their initial investigation suggests that the crater was formed not by a meteorite impact but by an explosion of underground gas hydrates. The research team led by Vladimir Pushkarev, director of the Russian Center of Arctic Exploration, believes the sudden appearance of the chasms does not present any danger.
