Scientists predict the Axial Seamount, an underwater volcano off the Oregon coast, may erupt soon. Despite increased activity, it poses no threat to the public.

The Pacific Northwest's most active underwater volcano is showing signs of an impending eruption.

For decades, scientists have been monitoring the massive underwater volcano, and recent activity shows that it might be ready to erupt.

The volcano, known as Axial Seamount, is located nearly 1 mile (1.4 kilometers) underwater on a geological hot spot, where searing gushes of molten rock rise from Earth’s mantle and into the crust.

Scientists at UW's Cabled Array, one of the world's largest ocean observatories monitoring this active volcano, have seen potential eruption signs in recent months.
