Axial Seamount lies about 300 miles (470 km) off Oregon’s coast, deep beneath the Pacific Ocean. For years, it’s been closely watched through a high-tech network of underwater sensors and ...

Axial Seamount is closely monitored. It was chosen as the site of the world's first underwater volcano observatory. Now a constant stream of real time data is provided from the seafloor thanks to ...

The Axial Seamount, an underwater volcano 300 miles off the coast of Oregon, U.S., is stirring and will likely erupt again in 2025. Because Axial Seamount dwells nearly 5,000 feet below the ...

Here's what to know. A 3D bathymetric map showing the shape and summit caldera of the Axial seamount, 300 miles off Oregon's coast. Warm colors indicate shallower depths, cool colors are deeper.

Before the 2015 eruption, Axial Seamount had last spilled lava over the seafloor in 2011—an eruption that scientists discovered completely by accident. Unlike volcanoes on land, submarine ...

Axial is the world’s most extensively studied undersea volcano because more than 660 miles of undersea cables crisscross it, sending a steady stream of real-time data about the area to scientists.

The volcano, named Axial Seamount, sits on the Juan de Fuca Ridge about 300 miles off the coast of Astoria, Oregon. In the last 30 years, Axial has erupted three times — in 1998, 2011, and 2015.

A massive seafloor eruption at Axial Seamount could reshape Earth in 2025, with hundreds of daily earthquakes signaling an impending eruption. Rising magma and quake surges forecast a major change.

A decade plus ago, Axial Seamount became one of nature’s own laboratories for geoscientists, who have made the site one of the world’s most heavily monitored submarine volcanoes.

Letter Published: 10 June 2012 Repeat bathymetric surveys at 1-metre resolution of lava flows erupted at Axial Seamount in April 2011 David W. Caress, David A. Clague, Jennifer B. Paduan, Julie F ...

Axial Seamount has erupted three times in the past 30 years — in 1998, 2011, and 2015. The submarine volcano isn’t the only seismic activity West Coasters may have in store.
