PAHOA, HI - MAY 21: Lava from a Kilauea volcano fissure flows past downed trees towards the Pacific Ocean, on Hawaii's Big Island, on May 21, 2018 near Pahoa, Hawaii. Officials are concerned that 'laze', a dangerous product produced when hot lava hits cool ocean water, will affect residents. Laze, a word combination of lava and haze, contains hydrochloric acid steam along with volcanic glass particles. (Photo by Mario Tama/Getty Images)
