Believed to have formed in the 1960s, the Batagaika crater is expanding due to melting of permafrost caused by deforestation, according to current theories. However, conflicting information suggests that the crater’s origin may be older: erosion processes were noticed in 1947.
Regardless of exactly how the crater formed, its growth is cause for concern. Scientists estimate that its volume is increasing by about one million cubic meters per year, with two-thirds of this figure explained by thawing permafrost. Its expansion poses environmental risks, including increased greenhouse gas emissions and changes to local river systems.
While the crater’s growth may eventually stabilize as the permafrost approaches its limit, it is necessary to reverse the effects of climate change to prevent further expansion.
