Sheveluch is one of the most active volcanoes in Kamchatka. Its modern edifice includes three main elements: Old Sheveluch, an ancient caldera and Young Sheveluch. On the southeastern slope of Old Sheveluch, there is a group of ancient extrusive domes (from south to north): Sherokhovataya, Krasnaya, Karan, Sopochka na sklone. Only in the area of the Karan dome, there are heated areas with mofets temperature of 70-96 °C. After the powerful explosive eruption of the Sheveluch volcano in April 2023, the gas-steam activity of the Karan dome intensified, and a thermal anomaly began to be noted in satellite images of the area of this dome. On April 26, 2024, in a satellite image of JPSS 1 (Joint Polar Satellite System) at 15:07 UTC, KVERT (Kamchatkan Volcanic Eruption Response Team) scientists discovered a bright thermal anomaly in the area of the Karan dome, that is, they recorded on this day a unique phenomenon: the birth of a new volcanogenic formation — the new lava dome. It was given the name “300 years of RAS”. As of June 7, 2024, the size of the new dome was 800×500 m, and the area of the dome crown was 0.19 km2. The eruption of new lava dome “300 years of RAS” continues.
