About NW Eifuku
NW Eifuku is a stratovolcano rising to -1,535 meters (-5,036 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
NW Eifuku is located in United States, within the Mariana Volcanic Arc of the broader Northwestern Pacific Volcanic Regions. Situated at 21.48° N, 144.04° E in the Northern Hemisphere, the volcano lies within a tropical climate zone. With an elevation of -1,535 meters — below sea level — NW Eifuku 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
NW Eifuku 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 NW Eifuku, 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 basalt / picro-basalt, 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
NW Eifuku is a small submarine volcano that exhibits vigorous thermal activity. The summit of the basaltic-to-andesitic volcano lies 1,535 m below the ocean surface; the seamount lies at the NW end of a 25-km-long chain of submarine volcanoes that includes Eifuku and Daikoko. Hydrothermal fluid emission includes liquid carbon dioxide bubbles venting from "white smokers," one of only two places where natural liquid carbon dioxide emission has been observed. The hydrothermal field, named Champagne, was discovered during a 2003 NOAA expedition and lies in the steep headwall of a slope-failure scarp that cuts the summit and SW side of the volcano.

Frequently Asked Questions About NW Eifuku
Is NW Eifuku an active volcano?+
NW Eifuku 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 NW Eifuku?+
NW Eifuku has a summit elevation of -1,535 meters (-5,036 feet) above sea level. With an elevation of -1,535 meters (below sea level), this is a submarine or submerged volcanic feature.
What type of volcano is NW Eifuku?+
NW Eifuku 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 NW Eifuku located?+
NW Eifuku is located in United States, in the Northwestern Pacific Volcanic Regions. More specifically, it lies within the Mariana Volcanic Arc. Its exact coordinates are 21.485° latitude, 144.043° longitude.
Is it safe to visit NW Eifuku?+
NW Eifuku 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.
