stratovolcan 888 m / 2,913 ft Kunashir, Iles Kuriles, 43.98°N / 145.74°E Liste des éruptions: 1901(?), 1880, 2270 BC ± 50
2000 seismic swarm
Earthquake swarms occurred at Mendeleev volcano in the summer of 2000. The earthquakes were less than 20 km deep.
1990 increased fumarolic activity
In 1990, activity in the NW fumarolic field of Mendeleev volcano increased. Molten sulphur was observed at the upper basic fumarole. A new thermal area was observed as well as an increase of temperatures of other hot springs.
1987 earthquake swarm
An earthquake swarm at 10 km depth occurred at Mendeleev volcano during 4-5 May 1987. In the same month, a small steam-gas emission occurred in the NE fumarole field.
1984 temperature increase
In 1984, temperatures of the Revushchaya fumarole reached 130 deg C and produced a flow of molten sulphur.
1978 fumarole activity
On 15 August 1978 the temperature of the Spokoiny fumarole in the NW field increased to 113 deg C and was accompanied by the appearance of molten sulphur.
1977 earthquake swarm
In February-April 1977, a seismic swarm with more than 200 earthquakes occurred at Mendeleev volcano.
The earthquakes were caused by drilling at Goryachy Plyazh geothermal field. In late August 1977, harmonic emissions of steam-and-gas plumes which reached up to 150-200 m height occurred at the NE fumarole field.
In 1946, local inhabitants near Mendeleev heard a roar produced by escaping hot gases and steam from the NE fumarole field.
Thundering noises were reported from Mendeleev volcano in 1901, indicating a possible eruption.
A small phreatic explosion happened at Mendeleev volcano in 1880 from the NE fumarolic field.
