The video was captured on May 19, 2018 at 3:47 pm HST by the Hawaiian Volcano Observatory. The large chunk of dark rock in the lower left part of the clip is spatter fragments from the eruption.
In addition to fears of lava flows, the volcanic activity is also releasing a gas called “laze,” which consists of hydrochloric acid and steam mixed with glass particles and is extremely hazardous to the lungs, eyes, and skin.
