The Axial Seamount is predicted to erupt in 2025, presenting a rare opportunity for scientists to test their models—tools that hold the potential to save lives.

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.

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.

Scientists are predicting an undersea volcano known as Axial Seamount, located just off the coast of Oregon, will erupt in 2025. Axial is the most active

An undersea volcano off Oregon's coast will probably erupt in 2025, scientists say. The volcano, known as Axial, is a seamount 300 miles (480 kilometers) west of Cannon Beach, Oregon. The Axial seamount erupts regularly — it rumbled to life in 1998,
