Grozny volcano (Etorofu Yake-yama in Japanese) in central Iturup Island, Kuriles is one of the most frequently active volcanoes of the volcanic island chain.
It is a complex of 2 volcanoes: Ivan Grozny volcano and Tebenkov (also known as Odamoi-san) volcano.
Ivan Grozny volcano has a 3-3.5 km diameter caldera open to the south and includes the andesitic Grozny lava dome, whose name is also used for the whole complex. All known historic eruptions took place from Ivan Grozny volcano.

Introduction:

To the NE, there are several other lava domes which are less than 10,000 years old. Their formation modified the shore of a former lake at the northern side of the caldera to extremely sinuous shape.
The forested andesitic Tebenkov volcano is located immediately NE of the Grozny dome complex. Machekh is a crater immediately south of Tebenkov and has strong fumarolic activity.
