Buildings on Yamal may collapse due to thawing of permafrost

Scientists from the Scientific Center for the Study of the Arctic stated that the melting of permafrost could lead to disruption of stability or destruction of infrastructure in the Yamal-Nenets Autonomous.

Yaroslav Kamnev, Candidate of Physical and Mathematical Sciences, said that an increase in the depth of seasonal thawing of permafrost will surely affect the entire infrastructure of the Yamalo-Nenets Autonomous Okrug. Perhaps some buildings will lose their stability, and some will begin to collapse. Linear objects such as roads and pipelines are particularly susceptible to this.

Kamnev said that, compared to 2016–2018, in 2020, the depth of permafrost thawing increased in Yamal. The expert is assured that in the future the permafrost will disappear altogether, but it is not yet possible to say when exactly this will happen.

One reason is the rise in average annual temperatures across the planet over the past 50 years. In the Arctic regions, this effect is more pronounced.

Scientists of the Yamalo-Nenets Autonomous Okrug are closely monitoring the dynamics of changes in the depth of the active layer. According to Kamnev, many thermometric wells have been installed in Yamal. In order to track the dynamics of changes in the depth of the active layer, the international program CALM (Circumpolar Active Layer Monitoring) was created.
