PBS News Hour

The challenges of wiring up an undersea volcano

Season 2015 Episode 1881 | 7m 36s

Hundreds of miles off the coast of Oregon and Washington, there's an undersea volcano known as Axial Seamount. Two months ago when it began spewing lava, it wasn't a secret to a group of scientists engaged in a groundbreaking research project. Hari Sreenivasan reports on their Cabled Observatory -- a network of sensors, moorings and cameras that offers views of a little-known world.
