Udina (Russian:Удина) is avolcanicmassif located in the central part of theKamchatka Peninsula,Russia. It comprises two distinct conicalstratovolcanoes:Bolshaya Udina, standing at 2,920 meters, andMalaya Udina, with a height of 1,945 meters.
Malaya Udina, the smaller of the two, is abasaltic volcano located at the eastern end of the complex, rising above a low saddle. Its flanks are dotted with small lava domes, characteristic of its formation.[2] This volcano is part of theVolcanoes of Kamchatka, a UNESCOWorld Heritage site, recognized for its geological significance and natural beauty.
Bolshaya Udina, the larger and western volcano, is composed primarily ofandesitic rock and features a prominentlava dome on its southwestern flank. Although it was long considered extinct, Bolshaya Udina surprised the scientific community when it exhibited signs of seismic activity, leading to its reclassification as an 'active' volcano in June 2019.[3] This reawakening has drawn attention to the potential hazards associated with the volcano, as well as the dynamic nature of the region's volcanic activity.
