Another giant crater appears on Siberia’s Arctic tundra


Another huge crater has been found on the Arctic tundra in Siberia. The latest depression, which is 650 feet wide, was found on the Gideon Peninsula – an area east of the Yamal Peninsula, where a 165-foot deep pit was recently discovered.

The latest pit was found by Oleg Shabalin from the head of the nearby Gida village. They found that this could occur through an explosive release of methane, as others have been known to develop, they reported this discovery. He said that this funnel of gases is “increasingly common in Russia’s tundra zone” The siberian times.

However, scientists have spoken of this depression, which is about 65 feet deep, but filled with mud, presumably formed as a result of warmer temperatures in which the permafrost melts with snow and the soil collapses.

Marina Leibman, from the Earth Cryosphere Institute, part of the Russian Academy of Sciences, website reported that the formation was a “thermokir” —a recession that builds through thawing of ice-rich permafrost.

“We’ve been studying thermocares for many years,” she was saying. “They became active in the hot year 2012. They look like huge landslides of a semi-circular shape with an outflow of ice. Previously such thermocycles were seen near the sea, now they are seen deep on land. Layers and warming. ”

Another well-known example of such depression is the “gateway to the underworld” pit, as it is known to locals in the eastern Siberian region. It is the largest pumafrost crater in the world at 3,200 feet long and 300 feet deep. In July, Science journal The reported rate of increase in this pit – officially called the Batagay pit – was increased. Its expansion rate before 2016 was around 32 feet per year, but now it is increasing between 29 and 45 per year.

The growth rate is believed to be due to rising global temperatures. Warmer summer and milder winters mean that the ground that has been frozen for thousands of years has begun to melt. In many Arctic regions, it is rich in permafrost ice. When the ice melts, the ground comes to a standstill – a geological process known as thermocarst. Experts pointed out earlier Newsweek In the coming years and decades, warmer temperatures will likely lead to the formation of many more such craters in the Arctic Kundra.

Scientists have also predicted that more craters formed through the explosive release of methane will appear in the future. These craters — the latest of which were announced in early September — when methane forms methane at the base of the ground below the surface. When sufficient pressure has formed, a large explosion is produced, which sends ice and mud hundreds of feet from the epicenter.

These craters are also thought to form as a result of warming temperatures, with more of these developing unfrozen ground. However, because many of these craters have only been discovered within the last decade, the link with climate change is still being investigated.

The discovery of the latest craters follows a record-breaking heatwave in Siberia, with temperatures in the Arctic city breaking 100 F. Heatwave has been directly linked to climate change, with one study saying the extreme view seen was “almost impossible”. Without this. Siberia has seen wildfires spread over an area larger than Greece, with fires dropping record levels of carbon dioxide in the process.
