Axial Seamount is one of countless volcanoes that are underwater. Scientists estimate that 80% of Earth's volcanic output — magma and lava — occurs in the ocean.

Axial Seamount is one of countless volcanoes that are underwater. Scientists estimate that 80% of Earth’s volcanic output — magma and lava — occurs in the ocean.

Because Axial Seamount is so far from shore and so deep, humans aren't expected to be impacted. But the impending magma flow generates pressure, heating sea water to more than 700 degrees Fahrenheit.

But Axial Seamount also happens to be located on the Juan de Fuca Ridge — an area where two massive tectonic plates (the Pacific and the Juan de Fuca plates) are constantly spreading apart, causing a ...

If you’ve never heard of the Axial Seamount, you’d be forgiven. But the underwater volcano has made national news recently after research suggested it is likely nearing its first eruption in ...

The Axial Seamount, an underwater volcano 300 miles off Oregon’s coast, may erupt soon. What it means for Washington, Oregon and the Pacific Northwest.

A researcher monitoring Axial Seamount, 300 miles off the coast of Oregon, says the eruption is expected to happen before the year is over. An underwater volcano in the Pacific Northwest is ...
