Axial Seamount (also Coaxial Seamount or Axial Volcano) is a seamount, submarine volcano, and underwater shield volcano [3] in the Pacific Ocean, located on the Juan de Fuca Ridge, approximately 480 km (298 mi) west of Cannon Beach, Oregon.

Jan 29, 2025 · The Axial Seamount, an underwater volcano located about 300 miles off the coast of Oregon, is displaying behavior that indicates an eruption is imminent in 2025, William Chadwick, research ...

Jan 6, 2025 · Axial Seamount sits under the Pacific Ocean about 300 miles from the U.S. coast. Since 1997, scientists have kept a careful eye on it using instruments that measure pressure on the ocean floor. Data shows that the volcano has been swelling, with changing rates that hint at an upcoming eruption.

Jan 28, 2025 · Earth bubbles and broils beneath an underwater peak called Axial Seamount, located 480 kilometers (300 miles) off Oregon's coast, causing it to swell in changing patterns that hint at impending strife. This has prompted scientists to predict the submerged volcano will erupt before the end of 2025 ...

Feb 1, 2025 · The Axial Seamount is a massive undersea volcano that reaches more than 3,600 feet above the seabed, 300 miles offshore. It last erupted in 2015 but has a history of more than 50 different ...

Jan 9, 2025 · The Axial Seamount, located 300 miles from the state’s coast and one mile beneath the Pacific Ocean’s surface, has been swelling at a steady rate for the past six months, with seismic activity...

Axial Seamount is the most active submarine volcano in the NE Pacific. It rises to a depth of 1400 m below sea level and is located about 300 miles off the coast of Oregon. Axial Seamount was the site of the world's first underwater volcano observatory called NeMO and has erupted most recently in 2015, 2011 and 1998.

Axial Seamount rises 700 m above the mean level of the central Juan de Fuca Ridge crest about 480 km W of Cannon Beach, Oregon, to within about 1,400 m of the ocean surface. It is the most magmatically and seismically active site on the Juan de Fuca Ridge between the Blanco Fracture Zone and the Cobb offset.

Jul 8, 2024 · The most active volcano in the Pacific Northwest is the Axial Seamount. It’s located 300 miles west of Astoria, Oregon, and a mile under the ocean. It’s erupted three times in the past 25...

Axial Seamount is the most robust volcanic system on the Juan de Fuca Ridge and it is seismically, magmatically, and hydrothermally active. It is located on the Juan de Fuca spreading center and hosts three active hydrothermal fields (ASHES, CHASM, and CASTLE).
