Underwater volcano Axial Seamount is still forecast to erupt by the end of this year, but the timing isn't imminent, one of the researchers told Yahoo News.

The Axial Seamount is an underwater volcano located about 300 miles off the coast of Oregon, and researchers at Oregon State University say it could erupt soon.

The Axial Seamount, located along the Juan de Fuca Ridge, is the most active submarine volcano in the northeast Pacific and has displayed a "pretty repeatable pattern," Chadwick said. In the last 30 years since monitoring began, it has erupted three times -- in 1998, 2011 and 2015.
