Overview

The 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 andesitic western volcano, Bolshaya Udina, has a prominent lava dome on its SW flank. The basaltic Malaya Udina rises above a low saddle at the eastern end of the complex; small lava domes also occur on its flanks.

    Regional Volcanic Activity
    The Northwestern Pacific Volcanic Regions contains multiple active volcanic systems. Cross-regional magma interactions and tectonic stresses can influence eruption patterns across the entire arc. Monitor regional seismic activity and volcanic alerts.

    About the Photo

    The Udina volcanic massif consists of two cones constructed along a WNW-ESE line at the south end of the Klyuchevskaya volcanic group, and SE of Tolbachik. The western cone is Bolshaya Udina, seen here from the south, and has a lava dome on the SW flank. The smaller Malaya Udina is out of view to the right.
