Overview

• The Axial Seamount, the most active underwater volcano in the Pacific Northwest, is expected to erupt by the end of 2025, according to scientists monitoring it.
• Located on the Juan de Fuca Ridge, the volcano has previously erupted in 1998, 2011, and 2015, following a consistent inflation and seismic activity pattern.
• Researchers have observed the volcano inflating as magma accumulates beneath its surface, a key indicator of an imminent eruption.
• The eruption, expected to occur about a mile underwater, will likely involve lava oozing onto the seafloor without causing a tsunami or posing a threat to human life.
• This event provides a unique opportunity for scientists to refine eruption prediction models, using real-time monitoring data from the world’s first underwater volcano observatory.
