Shiveluch is a volcano within the Kuril–Kamchatka volcanic arc which hosts tens of other volcanoes. As the Pacific Plate crust subducts deeper under the Okhotsk Plate, the melting points of minerals underground are reduced by other materials including water which results in the materials melting and forming into magma which rises onto the surface and forms the volcanoes.
The Kamchatka River and the surrounding central side valley are flanked by large volcanic belts containing around 160 volcanoes, 29 of them still active. The peninsula has a high density of volcanoes and associated volcanic phenomena, with 29 active volcanoes being included in the six UNESCO World Heritage List sites in the Volcanoes of ...

The June eruption follows nearby eruptions on 11 April 2023 in other volcanoes in the area. [7] A significant eruptive event occurred as part of ongoing activity on 1 November 2023, sending ash as high as 13 km (8.1 mi) above sea level and causing flight delays as far away as Vancouver, BC, on 4–5 November 2023.
Bezymianny volcano had been considered extinct until 1955. Activity started in 1955, culminating in a dramatic eruption on 30 March 1956. [2] [3] This eruption, similar to that of 1980 eruption of Mount St. Helens, produced a large horseshoe-shaped crater that was formed by collapse of the summit and an associated lateral blast.
The eruption continued for more than a month, as lava continued to flow from the fissures. [5] [6] [7] Lava flowed up to 20 kilometers (12 miles) from the line of fissures on the volcano's southern flank. According to the Kamchatka Volcanic Eruption Response Team, the eruption ended September 15, 2013.
