An undersea volcano off Oregon's coast will probably erupt in 2025, scientists say.

Deep below the Earth's surface, magma is churning and flowing into the Axial Seamount, an underwater shield volcano about 300 miles off the coast of Oregon. As the volcano grows and tremors increase,

Underwater eruptions may seem distant to folks on land, but they have global significance. The 2022 Hunga Tonga event, for example, triggered a tsunami that caused an estimated $90 billion in losses.

In the depths of the Pacific Ocean, 470 kilometers off the Oregon coast, a drama is unfolding. Axial Seamount, one of the most active underwater volcanoes in the world, is swelling with magma. Scientists believe it will erupt before the end of 2025—a bold prediction, but one based on decades of monitoring and a unique volcanic rhythm.

Axial Seamount is also the most active submarine volcano in the Pacific Northwest, having erupted multiple times since it was first discovered. Its most recent eruption was in April of 2015, causing thousands of underwater earthquakes to be detected and for the surrounding ocean floor to sink about 2 metres.

An underwater volcano off the coast of Oregon might erupt soon. Researchers studying it predict that it will erupt before 2025 is wrapped up.
