Siberia, a vast and cold region of Russia, currently remains mysterious to the world. In recent years, the construction of many big potholes here has worried the world. In Russia these craters are called “Bulgas”. The team of scientists and geologists is now busy solving the mystery of why this is happening and what kind of impact it is having on the Earth.
Why are potholes forming?
Large craters are being formed in Siberia mainly due to melting of permafrost. If you do not know about permafrost, then let us tell you that permafrost is a layer which remains permanently frozen and traps carbon dioxide and methane gases in it for thousands of years. When the temperature on Earth increases due to climate change, this permafrost starts melting and then big craters start forming.
Understand the entire process of pothole formation
Actually, when the permafrost melts, the carbon dioxide and methane gases trapped in it start coming out. These gases gradually create pressure inside the ground and when this pressure becomes too high, it blows up the ground surface. It’s like an explosion.
Only after this explosion a big crater is formed at that place. After the formation of the crater, carbon dioxide and methane gases keep coming out of it continuously. Scientists believe that these gases are ruining the Earth’s atmosphere.
First crater formed in 2014
In the year 2014, a huge crater was seen for the first time in Siberia. After this many more pits were formed in this area. Scientists believe that these potholes may increase even more in the coming years. According to Russian scientists, these potholes are indicating climate change not only in Siberia but at the global level.
