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 · The volcano, tucked underneath a submerged peak called Axial Seamount, is the most active volcano in the Pacific Northwest. Seismic activity, including hundreds of small earthquakes a day, indicate an eruption may be forthcoming — perhaps by the end of 2025, according to a blog kept by Bill Chadwick, a volcanologist who’s been closely ...

In the past 15 years, three separate volcanic eruptions have been detected in the NE Pacific by a formerly top-secret U. S. Navy system originally designed to detect and track submarines. The most recent eruption occurred in 1998 on the summit of a large seamount called Axial Volcano.

Axial volcano lies along the central Juan de Fuca Ridge crest about 480 km W of the Oregon coast. The summit reaches about 1.4 km below the ocean surface and is marked by a 3 x 8 km caldera (center). The caldera opens to the SE and has caldera walls up to 150 m high.

Jan 28, 2025 · "Axial is the most active volcano in the Northeast Pacific which maybe some people don't know, because it's hidden under the ocean," volcanologist Bill Chadwick told Jenn Chávezin in the Oregon Public Broadcasting podcast. The shield structure of the submerged peak indicates the mountain was formed from thin lava. This means the eruption will ...

It represents the product of intense volcanic activity from the Cobb-Eikelberg hotspot juxtaposed on the extensional field of the spreading center. Axial Volcano was first studied in the late 1970s and then mapped in greater detail by NOAA/VENTS with SeaBeam in the early 1980s.

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...

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 ...
