Udina

Udina (Russian: Удина) is a volcanic massif located in the central part of the Kamchatka Peninsula, Russia.

Malaya Udina, the smaller of the two, is a basaltic volcano located at the eastern end of the complex, rising above a low saddle.

Bolshaya Udina, the larger and western volcano, is composed primarily of andesitic rock and features a prominent lava 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.
