Scientists from Oregon State University claim to have made the first successful forecast of an underwater volcanic eruption.

They have been studying the Axial Seamount for the last 13 years and had predicted it would erupt before 2014.

Now footage captured by the team shows how lava has spewed from a vent in the seamount to spread 1.2 miles (2km) across the ocean floor.
