Scientists have finally figured out what caused the mysterious craters in Siberia. Surprisingly, these massive pits in the ground are also a result of climate change.

The first of these craters was found in 2014 in Siberia’s Yamal Peninsula. Several more of them were found in the following years. Geologists concluded that they were the result of some kind of explosions.

These craters in Siberia are quite large, with some of them measuring as deep as 165 feet (50 metres). The cause of the explosion was not clear yet.&nbsp;

After scientists detected high levels of methane in the regions, they theorised that the combustible gas was being released because of the rise in the average temperature. Notably, the Siberian permafrost is hiding large amounts of methane. However, later studies found that permafrost alone could not have caused such blasts.

A team of chemical engineers has now published its findings in Geophysical Research Letters, saying that rapid underground pressure changes caused the explosions.

"There are very, very specific conditions that allow for this phenomenon to happen," Ana Morgado, a chemical engineer at the University of Cambridge who worked on the study, said in a press release. “We’re talking about a very niche geological space.”

The team examined the composition of the ground in and around the craters. Chemical reactions were ruled out as the reason and they believed that there had to be a physical source for them which they found beneath the permafrost that sits under the topsoil.&nbsp;

<h2>Cause for craters in Siberia found deep inside Earth</h2>

While the latter thaws and refreezes, the former remains permanently frozen. Under permafrost lies cryopegs, a geologic layer comprising salt that doesn’t freeze.

In the Yamal Peninsula, cryopegs are about three feet thick and located as deep as 165 feet underground. Under this layer hides another layer filled with crystalised methane.

These layers have existed in this state for several years. However, the warming climate is now changing their equation, something that has been happening since the 1980s.

Scientists found the water in the topsoil had&nbsp;become meltier and trickled deeper below, reaching the cryopegs. This caused a buildup and increased the pressure in cryopegs.&nbsp;

This created cracks on the surface, causing the pressure to drop quickly. The gas is then forcefully released from the ground, creating an explosion and the mystery craters.&nbsp;
