Mysteries of massive holes forming in Siberian permafrost unlocked by scientists


Mysteries of massive holes forming in Siberian permafrost unlocked by scientists
Another massive crater appeared violently and explosively in the Siberian tundra in 2020, leaving a gaping circular scar in the empty and eerie landscape. It was the 17th hole to appear in the Russian Arctic since the first was spotted in 2013.

The massive crater appeared violently and explosively in the Siberian tundra last year a powerful blowout of methane gas throwing ice and rock hundreds of feet away and leaving a gaping circular scar in the empty and eerie landscape.
It was the 17th hole to appear in the remote Yamal and Gyda peninsulas in the Russian Arctic since the first was spotted in 2013, mystifying scientists. The craters are ....

Some 20 large craters have formed in recent years after explosions of bulging mounds in areas of the Russian Arctic. The cause is believed to be a build up of methane gas triggering blowouts which send ice and frost soil hundreds of metres from the epicentre.
In summer 2020, researchers from ....

The crater was dubbed Crater 17 (C17) as 16 similar objects have been discovered in the region since 2013.

Russian scientists believe that a massive crater above the Arctic Circle described as a “pit to hell” was formed as a result of an explosion caused by built-up methane.
The researchers based their conclusions on a 3D model they created from drone footage from inside the well-preserved crater that has not yet eroded or filled with water. Satellite images revealed that the crater formed in Siberia’s extreme northwest between May and June 2020, the researchers wrote in a paper published in the journal Geosciences last week. ....
