It was called “300 years of the Russian Academy of Sciences”
New lava dome – rising in the form of viscous lava – formed on the southwestern slope of the Shiveluch volcano.

It turns out that people “live” on a large volcano. smaller lava domes – they are formed as a result of squeezing viscous lava out of a volcanic channel. High viscosity does not allow the lava flowing from the vent to spread; it creates a dome, which then slowly cools at the site of the outflow.
On the southwestern slope of Shiveluch alone there are four such domes: Sherokhovataya, Krasnaya, Karan and Sopochka. And on one of them, Karan, at the end of last year a new heated platform was formed.
As reported in the Russian Academy of Sciences, the site of a potential new vent was discovered using satellite monitoring data by employees of the Institute of Volcanology and Seismology of the Far Eastern Branch of the Russian Academy of Sciences, the Computing Center of the Far Eastern Branch RAS, Institute of Space Research RAS and Scientific Research Center «Planet». This happened last year. And in April 2024, experts recorded a sharp increase in the temperature difference between the thermal anomaly and the background from 8 to 95 degrees Celsius. The day this was recorded – April 26 – is considered the birthday of the new lava dome. It was called «300 years of the Russian Academy of Sciences» in honor of the anniversary of the Russian Academy of Sciences celebrated this year.
By the beginning of June 2024, its height reached 100 meters, and the dimensions of the base — 800×500 meters.
