Poised some 300 miles off the coast of Oregon, one mile beneath the sea, yet rising 3,600 feet high, and spanning 1.2 miles across, one of the world’s most active volcanoes rests. It’s waiting, gurgling with seismic activity, preparing for a possible eruption sometime this year, according to scientists.

Frequent earthquakes 300 miles off the coast of Oregon signal escalation for the underwater volcano named Axial Seamount.

An Oregon State University scientist has predicted a volcanic eruption in 2025. But at about one mile under the ocean, the volcano isn’t considered a threat.

The colossal Axial Seamount, one of the most active and best-monitored underwater volcanoes in the world, could erupt in a similar fashion to Hawaii's Mauna Loa

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,
