About Daikoku
Daikoku is a stratovolcano rising to -323 meters (-1,060 feet) in United States'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
Daikoku is located in United States, within the Mariana Volcanic Arc of the broader Northwestern Pacific Volcanic Regions. Situated at 21.32° N, 144.19° E in the Northern Hemisphere, the volcano lies within a tropical climate zone. With an elevation of -323 meters — below sea level — Daikoku is a submarine or submerged volcanic feature. Submarine volcanoes make up the majority of Earth's volcanic activity, though most eruptions go unobserved beneath the ocean surface. 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
Daikoku 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 Daikoku, 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 conical summit of Daikoku seamount lies along an E-W ridge SE of Eifuku and rises to within 323 m of the sea surface. A steep-walled, 50-m-wide crater on the N flank, about 75 m below the summit, is at least 135 m deep and was observed to emit cloudy hydrothermal fluid. During a NOAA expedition in 2006, scientists observed a convecting black pool of liquid sulfur with a partly solidified, undulating sulfur crust at a depth of 420 m below the summit. Gases, particulates with the appearance of smoke, and liquid sulfur were bubbling up from an edge of the sulfur pool.

Frequently Asked Questions About Daikoku
Is Daikoku an active volcano?+
Daikoku is not currently classified as active. Its activity evidence is listed as "Unrest / Holocene." No recorded eruptions have been documented. However, no volcano is ever considered permanently extinct.
How high is Daikoku?+
Daikoku has a summit elevation of -323 meters (-1,060 feet) above sea level. With an elevation of -323 meters (below sea level), this is a submarine or submerged volcanic feature.
What type of volcano is Daikoku?+
Daikoku 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 Daikoku located?+
Daikoku is located in United States, in the Northwestern Pacific Volcanic Regions. More specifically, it lies within the Mariana Volcanic Arc. Its exact coordinates are 21.324° latitude, 144.194° longitude.
Is it safe to visit Daikoku?+
Daikoku 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.
