May 20, 2025 · A mysterious and highly active undersea volcano off the Pacific Coast could erupt by the end of this year, scientists say. Nearly a mile deep and about 700 miles northwest of San Francisco, the ...

Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation, known as mid-ocean ridges. The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth. [1]

3 days ago · OREGON – Axial Seamount, an active underwater volcano located approximately 300 miles due west of Astoria, Oregon, is showing signs that have led scientists to forecast a potential eruption. The volcano, which sits about a mile below the ocean surface, is described as “pretty much continuously active,” either erupting or preparing for its next event. […]

May 8, 2025 · Things are heating up hundreds of miles off the coast of Oregon, where a large undersea volcano is showing signs of impending eruption, scientists say. The volcano, known as Axial Seamount,...

May 10, 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 29, 2025 · Scientists are predicting that a mile-deep volcano off the U.S. West Coast will erupt this year. 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 associate at the Oregon State University, told ABC News.

Submarine volcanoes, or ‘underwater volcanoes’, are vents or fissures located underwater. They act in ways different from subaerial volcanoes. Learn about this awe-inspiring force of nature and understand their impact on our ocean ecosystem.

May 16, 2025 · The volcano is thousands of feet below the ocean’s surface, so it poses no danger to people. But under all that water, a dramatic eruption is brewing.

May 1, 2025 · Axial Seamount poses no threat to the public, as it sits too deep in the ocean and too far from shore to cause any harm, or for the public to even notice the volcano is erupting. It was announced in December 2024 that the underwater volcano was creeping toward an eruption, the first since 2015.

May 14, 2025 · Axial Seamount is located about 300 miles (480 km) off the coast of Oregon and is the most active submarine volcano in the northeast Pacific Ocean, with known eruptions in 1998, 2011, and 2015. From studying the volcano’s past behavior, scientists learned that Axial has effusive lava flows, like those you see at Kīlauea, not explosive ...
