About Tana
Tana is a stratovolcano(es) rising to 1,170 meters (3,839 feet) in United States's North America Volcanic Regions. No historical eruptions have been recorded, though the volcano is classified based on geological evidence of past activity.
Geography & Climate
Tana is located in United States, within the Aleutian Ridge Volcanic Arc of the broader North America Volcanic Regions. Situated at 52.83° N, 169.77° W in the Northern Hemisphere, the volcano lies within a temperate climate zone. With a summit elevation of 1,170 meters above sea level, Tana 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
Tana 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 United States near Tana, 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 rhyolite, a silica-rich volcanic rock associated with highly viscous magma. Rhyolitic eruptions can be extremely explosive and are responsible for some of the largest volcanic events in Earth's history, including supervolcanic caldera-forming eruptions. The high silica content traps dissolved gases, building enormous pressure that can lead to catastrophic explosive releases.
GVP Reference Summary
The Tana volcanic complex forming the eastern half of the Chuginadak Island, opposite the conical Cleveland stratovolcano, is composed of two prominent E-W-trending volcanoes. The complex shows evidence of glacial erosion, but highly irregular coastlines forming peninsulas west of Applegate Cove on the NW side of the complex and Concord Point on the south side imply lava flows of mid- to late-Holocene age (Nye 2007, pers. comm.). Prominent lava flow levees are visible near Concord Point, where a low-silica rhyolite sample was obtained. The undissected cone and youthful crater forming the western summit also imply a post-glacial age, and youthful cinder cones also lie east of the isthmus between Cleveland and Tana volcanoes.

Frequently Asked Questions About Tana
Is Tana an active volcano?+
Tana 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 Tana?+
Tana has a summit elevation of 1,170 meters (3,839 feet) above sea level. At 1,170 meters, it is a moderately sized volcanic peak, roughly comparable to Mount Vesuvius (1,281m).
What type of volcano is Tana?+
Tana is classified as a Stratovolcano(es). Stratovolcano(es) volcanoes have distinct geological characteristics that set them apart from other volcanic types.
Where is Tana located?+
Tana is located in United States, in the North America Volcanic Regions. More specifically, it lies within the Aleutian Ridge Volcanic Arc. Its exact coordinates are 52.830° latitude, -169.770° longitude.
Is it safe to visit Tana?+
Tana can generally be visited, but as with any volcano, visitors should check local conditions and any advisory notices before traveling. United States may have specific regulations for accessing volcanic areas. Guided tours are often the safest and most informative way to experience a volcano.
