Description
The young subterminal crater of the volcano Bogdan Khmelnitsky is located in an ancient ruined cone, in the near-shore part of which is the source of the southern Chirip stream. The lava eruptions of the cone of the volcano were very plentiful, lava flows completely blocked the entire southern part of the ancient massif: in the east and in the west they reach the sea. The subterminal crater has a diameter of about 250 - 270 m with a depth of 30 - 35 m. In this crater there is a funnel of the last eruption with a diameter of about 100 m and a depth of up to 25 m. In the vicinity of this funnel slags, lapilli and bombs, as well as large blocks with a surface, were deposited type of bread crust. Lavas of the cone Bogdan Khmelnitsky belong to bipyroxene andesites.

Potencial Hazard
Ash clouds, ash falls, hot avalanches and lahars are a potential hazard associated with explosive eruptions of this volcano. The volcano poses a potential hazard to international and local airlines passing in the Kuriles region, since the height of its ash emissions can reach 10 km above sea level, ash plumes and clouds can drift hundreds of kilometers from the volcano in different directions. In addition, the outflow of lava flows onto the slopes of the volcano and the surrounding area is possibly.
