Mysterious Siberian sinkholes emerge

Mysterious three giant sinkholes in Siberia emerge from one place to another as peoples baffled of the unexplained phenomena. It forms like a crater, and scientist predicted this is how a crater was made, not by force of meteorites from space that fall into Earth but has something to do in the surface. And others are skeptical, they have in mind that it was planned by aliens.

In the middle of July, sinkholes started to draw in Yamal Peninsula that was approximately 260 feet wide, then in the Taz district was about 50 feet, then another comes in Taymyr Peninsula with 330 feet.

Russian scientist has launched an investigation to find out more. Helicopter video footage of the first hole shows it is surrounded by a mound of loose dirt that appears to have been thrown out of the hole.

“My personal opinion is it’s some type of sinkhole,” said Vladimir Romanovsky, a geophysicist who studies permafrost at the University of Alaska Fairbanks. Sinkholes are pits in the ground formed when water fails to drain away.

The water likely came from melting permafrost or ice, said Romanovsky, who has spoken with the Russian scientists investigating the site. But whereas most sinkholes suck collapsed material inside, “this one actually erupted outside,” he told Live Science. “It’s not even in the [scientific] literature. It’s pretty new what we’re dealing with,” he added.

From the photo of the Yamal crater, “it’s obvious that some material was ejected from the hole,” Romanovsky said. His Russian colleagues who visited the site told him the dirt was piled more than 3 feet (1 m) high around the hole’s edges.

The crater’s formation probably began in a similar way to that of a sinkhole, where water (in this case, melted ice or permafrost) collects in an underground cavity, Romanovsky said. But instead of the roof of the cavity collapsing, something different occurred. Pressure built up, possibly from natural gas (methane), eventually spewing out a slurry of dirt as the ground sunk away. Anna Kurchatova, a scientist at the Sub-Arctic Scientific Research Center in Russia, made a similar observation to The Siberian Times.

The development of permafrost sinkholes could be one indication of global warming, Romanovsky. “If so, we will probably see this happen more often now.”
