Axial Seamount: One of the World's Most Active Underwater Volcanoes Approaching New Eruption in 2026

One of the most active underwater volcanoes globally, Axial Seamount, located approximately 480 kilometers off the coast of Oregon, is now estimated to have an increased probability of erupting around 2026, based on the latest scientific data. Experts had previously warned of a possible eruption as early as late 2025, but the new estimate places the timeframe in mid-to-late 2026. However, it is emphasized that this is not an immediate or dangerous situation for humans. Axial Seamount is known for its intense activity, with recorded eruptions in 1998, 2011, and 2015. Recent increases in seismicity and the steady uplift of the seafloor indicate magma rising and an impending eruption. During an underwater eruption, lava cools rapidly due to the low water temperature, forming 'pillow-like' structures. This process is destructive to marine organisms nearby, while also enhancing the activity of hydrothermal vents and the creation of 'black smokers'. Following each eruption, the volcano's caldera collapses, causing the seafloor to subside. While there is a theoretical risk of a tsunami in the event of a large collapse, scientists emphasize that such a scenario is highly unlikely. The volcano is not considered an immediate threat to human life due to its depth and distance from the coast.
