The regions of Yamal and Gydan in Siberia have about 7,000 underground gas bubbles that could explode anytime now. These could put the residents of the said areas in danger.
The bubbles approximately have 1,000 times more methane and 25 times more CO2 than the surrounding air, according to a study conducted last year. The study also indicated that climate change is the chief culprit.
A spokesperson for the Russian Academy of Science stated that their appearance at increasing altitudes is associated to thawing permafrost, which is linked to the rising temperature in the north of Eurasia during some last decades. It is theorized that the craters or the pockmarks shape when the "pingos," which are dome-shaped mounds covering ice, explode because of the pressure of methane gas that is discharged as the permafrost thaws, according to Huffington Post.
Currently, studies are now being conducted to examine this weird phenomenon and to identify which bubbles are dangerous to safeguard the residents. Titovsky said that they need to know which bumps are dangerous and which are not. He further said that the researchers are now working and identifying and structuring signs of potential threat. These include the highest height of a bump and pressure that the earth can endure.
