Researchers were alerted to the possible submarine eruption of the Axial Seamount, located about 300 miles (480 kilometers) off the West Coast, by large changes in the seafloor elevation and an increase in the number of tiny earthquakes on April 24.

Geologists Bill Chadwick, of the Pacific Marine Environmental Laboratory and Oregon State University, and Scott Nooner, of the University of North Carolina, Wilmington, successfully forecast the eruption in a blog post in September 2014, though they had presented their ideas at a meeting before then.

Axial Seamount is an underwater mountain that juts up 3,000 feet (900 meters) from the ocean floor, and is part of a string of volcanoes that straddle the Juan de Fuca Ridge, a tectonic-plate boundary where the seafloor is spreading apart.
