About Uratman
Uratman is a stratovolcano rising to 678 meters (2,225 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
Uratman is located in Russia, within the Kuril Volcanic Arc of the broader Northwestern Pacific Volcanic Regions. Situated at 47.12° N, 152.25° E in the Northern Hemisphere, the volcano lies within a temperate climate zone. With a summit elevation of 678 meters above sea level, Uratman is a moderately sized peak that remains accessible to hikers and researchers for much of the year. 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
Uratman 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 Uratman, 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 northernmost of volcanoes on Simushir Island, Uratman consists of an impressive 7.5-km-wide Pleistocene caldera that forms the NE tip of the island. Caldera walls rise 450 m above a 250-m-deep caldera bay. A narrow gap in the northern caldera rim provides sea-water access into the half-moon-shaped Brouton Bay, which fills the NW half of the caldera. A central somma cone, andesitic Uratman, has grown during the Holocene in the SE part of the caldera. Two cinder cones are located along the N flank of Uratman, and a lava dome was formed on its NW flank along Brouton Bay. No historical eruptions are known.

Frequently Asked Questions About Uratman
Is Uratman an active volcano?+
Uratman 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 Uratman?+
Uratman has a summit elevation of 678 meters (2,225 feet) above sea level. At 678 meters, it is a relatively low-elevation volcano.
What type of volcano is Uratman?+
Uratman is classified as a Stratovolcano. Stratovolcanoes (also called composite volcanoes) are steep, conical volcanoes built up by many layers of hardened lava, tephra, and volcanic ash. They are among the most common and dangerous types, known for explosive eruptions.
Where is Uratman located?+
Uratman is located in Russia, in the Northwestern Pacific Volcanic Regions. More specifically, it lies within the Kuril Volcanic Arc. Its exact coordinates are 47.120° latitude, 152.250° longitude.
Is it safe to visit Uratman?+
Uratman 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.
