Sinkhole scare: Mysterious giant crater emerges in Siberian village

A fresh giant crater has appeared in Siberia’s Novokuznetsk region. Measuring 20 meters in diameter and up to 30 meters in depth, the hole is unnerving the local population, who fear the next one might swallow their homes.

The mysterious sinkhole was first spotted by Rinat Sharifullin, a local man whose house is a mere 100 meters away from where it emerged. He blames the sagging of earth into abandoned mine tunnels snaking beneath the ground in the area.

“We have to get out of here”, Rinat’s wife Natalia told local media. “There are mines under our garden, closed down in the 1990s.”

Emergency ministry staff promptly arrived to the spot, fenced the crater away and filled it with earth. Experts are now investigating it to find out why it emerged.

The new crater emerged some 3,500 kilometers away from a group of similar holes not far from Gazprom’s Bovanenkovo gas field. There, about 20 ‘baby’ craters appeared in February around a giant one filled with water, which could mean there could be more to come in the new spot.

In either location, there’s no full certainty as to what caused them. While locals blame old mine shafts, geologists name another possible reason: methane emissions from permafrost melting due to global warming. Methane is a highly flammable gas, and locals are being advised to avoid using fire near the craters. This also makes it a dangerous job for scientists to study the holes.

Whatever the cause, such craters always appear in groups, says professor Vasily Bogoyavlensky from the Moscow State University of Oil and Gas. “I would compare them to mushrooms. If you find one, you will most likely discover a dozen more nearby.”

Geologists say similar craters in the past could have caused the formation of a number of lakes in Siberia’s Yamal peninsula.
