Kilauea volcano (Hawaii): the fire hose (March 2017)

For almost 3 months in early 2017, Kilauea volcano was the site of one of the most spectacular and rarest volcanic phenomena: a "fire hose" or lava hose shooting into the ocean. A major bench and cliff collapse on New Year 's Eve 2016 exposed the main active lava tube which had been feeding the ocean entry at rates of up to several cubic meters of very fluid, hot (approx. 1200 deg C) lava. The lava has been traveling underground from the vent on the east rift zone to the coast at 10 miles distance.
The collapse on 31 Dec also affected the submarine part of the coast, creating a very steep submarine slope. It took almost 3 months before the continuous addition of lava finally succeeded to create a new lava delta (bench), allowing the lava to encase itself, stopping the "fire hose" effect.
The pictures on the lower part of this page show one of the last days of the life of the fire hose (18 Mar) when a surge in the tube caused it to be particularly violent.
