The Axial Seamount is an active underwater volcano located about 300 miles off the coast of Oregon. It’s been closely studied due to its unpredictable eruptions. Initially, scientists thought it would erupt in 2025, but new data suggests an eruption is likely between mid-to-late 2026. The researchers at Oregon State University (OSU) are using advanced models and monitoring techniques to understand this volcano better.
Axial Seamount sits nearly a mile below the ocean surface, which makes tracking its activity tough. In the past 800 years, it has erupted around 50 times, with three significant eruptions in the last 30 years. Although scientists initially predicted an eruption in 2025, shifts in seismic data led them to adjust that estimate.
Researchers at OSU’s Hatfield Marine Science Center utilize the Regional Cabled Array, an impressive system of over 660 miles of underwater cables and 140 instruments that provide real-time data on the volcano’s behavior. Bill Chadwick, a volcanologist at OSU, noted that they’ve observed an inflation level similar to what occurred before the 2015 eruption. Even though the volcano’s inflation rate is steady, the seismic activity has been low. This means there’s no immediate danger, and eruptions won’t happen until at least late 2026.
To improve eruption predictions, OSU researchers are developing a new physics-based model. This innovative approach aims to make forecasting eruptions more accurate. By merging real-time data from the Regional Cabled Array with advanced mathematical models, they hope to uncover how magma moves, gas is released, and seismic activity occurs.
This model could not only apply to Axial Seamount but to other underwater volcanoes as well, increasing safety and preparation around these potentially dangerous areas.
Despite predictions of an upcoming eruption, there’s little cause for alarm for those near the coast. The depth of Axial Seamount means that any eruptions will mostly result in smaller seismic activity like minor earthquakes, which are unlikely to be felt on land. Eruptions will primarily reshape the seafloor, leaving the waters above safe and unaffected.
Studying underwater volcanoes like Axial Seamount is essential for several reasons. It helps scientists predict eruptions, understand seismic risks, and explore how volcanic activity influences the ocean ecosystem and the Earth’s crust. The ongoing research at OSU is setting the groundwork for better early-warning systems. In a world where understanding natural disasters can save lives and improve community resilience, the insights gained from Axial Seamount are invaluable.
