About Davidof
Davidof is a stratovolcano rising to 328 meters (1,076 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
Davidof is located in United States, within the Aleutian Ridge Volcanic Arc of the broader North America Volcanic Regions. Situated at 51.97° N, 178.33° E in the Northern Hemisphere, the volcano lies within a temperate climate zone. At just 328 meters above sea level, Davidof is a relatively low-elevation volcanic feature. Despite its modest height, it remains an active geological formation with the same underlying magmatic processes as its taller counterparts. 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
Davidof 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 Davidof, 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 no data (checked), which influences the viscosity of the magma and, consequently, the style of eruptions this volcano produces. Rock chemistry is one of the most important factors in determining whether a volcano erupts explosively or effusively.
GVP Reference Summary
A cluster of small islands between Segula and Little Sitkin in the western Aleutians, the largest of which is Davidof, are remnants of a stratovolcano that collapsed during the late Tertiary, forming a 2.7-km-wide caldera. The islands include Khvostof, Pyramid, Lopy, and Davidof; the latter three form the eastern rim of the mostly submarine caldera, sometimes referred to as the "Aleutian Krakatau." The islands were constructed above a roughly 100-m-deep submarine platform extending NW to Segula Island; the floor of the caldera lies 80 m below sea level. The islands are vegetated, but lava flows are recognizable, and Smith et al. (1978) suggested a possible Holocene age.

Frequently Asked Questions About Davidof
Is Davidof an active volcano?+
Davidof is not currently classified as active. Its activity evidence is listed as "Evidence Uncertain." No recorded eruptions have been documented. However, no volcano is ever considered permanently extinct.
How high is Davidof?+
Davidof has a summit elevation of 328 meters (1,076 feet) above sea level. At 328 meters, it is a relatively low-elevation volcano.
What type of volcano is Davidof?+
Davidof 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 Davidof located?+
Davidof 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 51.970° latitude, 178.330° longitude.
Is it safe to visit Davidof?+
Davidof 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.
