About Udina
Udina is a stratovolcano(es) rising to 2,886 meters (9,469 feet) in Russia's Northwestern Pacific Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Udina is located in Russia, within the Eastern Kamchatka Volcanic Arc of the broader Northwestern Pacific Volcanic Regions. Situated at 55.76° N, 160.53° E in the Northern Hemisphere, the volcano lies within a subarctic climate zone. At 2,886 meters above sea level, Udina rises above the surrounding terrain into montane or subalpine conditions. The elevation creates distinct ecological zones along its flanks, from forested lower slopes to exposed rocky terrain near the summit. The volcanic landform is characterized as a composite, which describes the physical shape and structure of the volcanic edifice as observed from the surface.
Geological Context
Udina sits in a subduction zone, where one tectonic plate dives beneath another, creating intense heat and pressure that generates magma. Subduction zones are responsible for many of the world's most explosive volcanoes and deadliest eruptions. For communities in Russia near Udina, this tectonic setting means the volcano is capable of producing powerful explosive eruptions, pyroclastic flows, and lahars that can threaten populated areas within tens of kilometers of the summit. The dominant rock type is andesite / basaltic andesite, a dark, fine-grained volcanic rock that forms from rapidly cooling, low-viscosity lava. Basaltic eruptions tend to be less explosive and produce fluid lava flows that can travel long distances. While less immediately dangerous than explosive eruptions, basaltic lava flows can destroy structures and infrastructure in their path, and volcanic gases released during these eruptions can affect air quality over a wide area.
GVP Reference Summary
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.

Frequently Asked Questions About Udina
Is Udina an active volcano?+
Udina is classified as active based on credible evidence of past eruptions. Although its last known eruption was in prehistoric times, volcanologists consider it capable of erupting again.
How high is Udina?+
Udina has a summit elevation of 2,886 meters (9,469 feet) above sea level. At 2,886 meters, it is comparable in height to many significant mountain peaks and stands well above the tree line.
What type of volcano is Udina?+
Udina is classified as a Stratovolcano(es). Stratovolcano(es) volcanoes have distinct geological characteristics that set them apart from other volcanic types.
Where is Udina located?+
Udina is located in Russia, in the Northwestern Pacific Volcanic Regions. More specifically, it lies within the Eastern Kamchatka Volcanic Arc. Its exact coordinates are 55.758° latitude, 160.527° longitude.
Is it safe to visit Udina?+
Udina can generally be visited, but as with any volcano, visitors should check local conditions and any advisory notices before traveling. Russia may have specific regulations for accessing volcanic areas. Guided tours are often the safest and most informative way to experience a volcano.
