BackgroundThe Udina volcanic massif consists of two conical stratovolcanoes constructed along a WNW-ESE line at the south end of the Kliuchevskaya volcanic group, SE of Tolbachik volcano. The western volcano, 2923-m-high andesitic Bolshaya Udina, has a prominent lava dome on its SW flank. The 1945-m-high basaltic Malaya Udina rises above a low saddle at the eastern end of the Udina complex; small lava domes also occur on its flanks. No historical eruptions have occurred from the Udina complex.
