A helicopter overflight of Kīlauea Volcano's lower East Rift Zone shows the interaction of lava
and seawater to produce a laze plume
. Laze is formed when lava enters the ocean. The interaction sends hydrochloric acid and steam with fine glass particles into the air. Laze drifts with the wind and can be a health hazard for people in the immediate vicinity of the plume, but it dissipates quickly downwind. Laze is irritating to the lungs, eyes and skin. The video also shows the rapid fragmentation of lava when it enters the ocean.
