This dramatic video shows huge plumes of steam on January 1 as lava flows into the ocean after a large section of a lava delta at the Kamokuna ocean entry of Kilauea in Hawaii Volcanoes National Park <a href="http://bigislandnow.com/2017/01/01/delta-collapse-closes-kamokuna-ocean-entry/" target="_blank">collapsed on New Year’s Eve</a>

After the so-called “bench collapse”, the viewing area at the National Park was closed as park rangers and <span class="caps">USGS</span> Hawaiian Volcano Observatory scientists surveyed the area.

A “bench” forms as lava flows over a seacliff into the ocean, forming an unstable ramp of rubble that can be undermined by landslides and slumps, causing a collapse. The collapse exposes the hot interior of the bench to the sea water, causing an explosion of acidic steam and rubble.
