Russian scientists from Moscow State University (MSU) and the Melnikov Institute of Permafrost Science of the Siberian Branch of the Russian Academy of Sciences, with the participation of colleagues from Germany, recorded the rapid growth rate of the Batagaysky failure, the world’s largest permafrost crater. In the world. The research was published in the scientific journal magazine Geomorphology.
Batagaysky crater is located in the Yanina Highlands in Yakutia. As a result of gradual collapse, 650 thousand-year-old layers of permafrost were exposed, which is the oldest permafrost in Siberia and the second oldest in the world.
The team found that one of the edges of the Batagai Gap is retreating at a rate of about 12 meters per year due to melting permafrost. As a result, the width of the crater increased by 200 meters in the last 10 years, reaching 990 meters.
Scientists say that an area of ​​ice and sediment equivalent to more than 14 Great Pyramids in Egypt melted during this time.
Researchers believe that the expansion of the Batagai crater will soon reach its limit.
Previous scientists I learnedHe says that about a quarter of the world’s population lives in areas where sinkholes and collapses are possible.
