The Medvezhia (Moyorodake in Japanese) volcano complex (including Medvezhii, Srednii, Kudryavy or Men’shoi Brat volcano) is one of the Kurile's most active volcanoes. It is located on the NE end of Iturup Island, Kurile Islands. It is remarkable for its high temperature fumaroles.
Medvezhia volcano has 2 overlapping calderas, 14 x 18 and 10 x 12 km in diameter, which were formed more than 10,000 years ago, and a row of 4 stratovolcanoes close to each other along a E-W line on the eastern side of the complex (from E to W): Medvezhii volcano, the highest and located outside the western caldera, Srednii, Tukap, and Kudriavy volcanoes.
All historic activity has been from Kudryavy volcano (Moyoro-dake in Japanese), which is younger than 2000 years only. Besides Kudryanvy, only Tukap volcano has active fumaroles.
Another vent of recent, but not historically observed activity is the Menshoi Brat lava dome inside the caldera.
|Volcano type||somma volcano normal or dormant|
|Summit elevation||1125 m / 3,691 ft|
|Medvezhia volcano eruptions||1999, 1958, 1883, 1778|
|Typical eruption style||explosive & effusive|
The caldera floor contains several lava domes, cinder cones and associated lava fields, and a small lake. The westernmost of the post-caldera cones, Menshoi Brat, is a large lava dome with flank scoria cones, one of which has produced a series of young (probably a few centuries old) lava flows up to 4.5 km long that reached Slavnoe Lake.
