About Axial Seamount

  • It is an underwater volcano located about 300 miles off the coast of Oregon, United States in the Pacific Ocean.
  • It is a shield volcano with a summit marked by a large caldera.
  • It rises to a depth of 1400 m below sea level.
  • It is formed by a hot spot, an area in the Earth’s mantle where hot plumes of molten material rise into the crust. 
  • It is located on the Juan de Fuca Ridge, the boundary between the Pacific and Juan de Fuca tectonic plates.
  • The volcano is home to hydrothermal vents, underwater hot springs where seawater is heated by magma and ejected in mineral-rich plumes. 
  • These vents support diverse marine life, including microbes that use volcanic gases for energy, forming the basis of an ecosystem that includes giant tubeworms, spider crabs, clams, fish and octopuses.
  • It is the most active submarine volcano in the northeast Pacific, with known eruptions in 1998, 2011, and 2015. 
  • While Axial Seamount’s eruptions are not dangerous to people on land, they offer valuable opportunities for scientific observation.
  • It is part of the Ocean Observatories Initiative (OOI) and hosts the world’s first underwater volcanic observatory called NeMO.
