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.

An increase in seismic activity has prompted predictions that a mile-wide submarine volcano named the Axial Seamount will erupt near the United States West Coast by year’s end. “The eruptions are pretty big,” Bill Chadwick, a volcanologist at Oregon State University who studies the fire-spouting formation, told KOIN.
