The volcano forms the southern extremity of Iturup Island

The volcano Berutarube is a gently sloping cone with a base diameter of 10–11 km and a flat crater about 1.2 km in diameter, in which there is a small heavily destroyed cone with a base diameter of about 1 km.

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.
