- VolcanoMendeleev (Rausu-dake in Japanese) is a low stratovolcano on Kunashir Island in the southern Kurile Islands, 40 km from Hokkiado in Northern Japan. The volcano is composed of 3 nested calderas measuring 6x9 km (the oldest caldera), 3x3.5 km, and 1x1 km (youngest caldera). A large sub-aerial eruption occurred during the formation of the youngest 1x1 km caldera. It was followed by the growth of an extrusive lava dome 2550 ± 40 years ago. The effusive activity continued for several centuries. Mendeleev volcano contains a shallow magma chamber at 4.5 km depth and a deep magma source at a depth of 30-60 km.
Volcano type stratovolcano normal or dormant Location Russia Summit elevation 888 m / 2,913 ft Mendeleev volcano eruptions 1901(?), 1880, 2270 BC ± 50 Typical eruption style explosiveMendeleev volcano is dominantly andesitic-dacitic in composition. A central cone formed inside the younger caldera and was breached to the west by a large debris avalanche about 4200 years ago. A lava dome that grew inside the avalanche scarp forms the 888 m high point of the volcano.
Additional lava domes in the northern part of the older caldera are considered to represent flank activity of the younger caldera. The only unambiguous historical eruption was a small phreatic explosion in 1880. 4 solfatara fields lie at the eastern and northern flanks of the central cone, and the Goriachy Pliazh geothermal field is located outside the caldera along the eastern coast.
