What Is Axial Seamount
Axial Seamount is an underwater volcano on the Juan de Fuca Ridge off the Oregon coast. It sits above a magma supply zone where tectonic plates spread apart. The seamount hosts a caldera and hydrothermal vents on its summit.
Eruption Forecast and Recent Activity
Scientists from NOAA and partner institutions monitor Axial Seamount with seafloor pressure sensors and acoustic instruments. The volcano has shown repeated inflation and deflation cycles that precede eruptions. Based on recent data, models indicate an expected eruption in the near future.

Why This Eruption Matters
An eruption at Axial Seamount can reshape the seafloor, alter hydrothermal vent fields, and affect deep-sea ecosystems. Researchers use these events to study magma movement, plate tectonics, and undersea hazards. The data also help improve long-term forecasts for similar seamounts worldwide.
