This Friday, May 4, 2018, aerial image released by the U.S. Geological Survey, at 12:46 p.m. HST, a column of robust, reddish-brown ash plume occurred after a magnitude 6.9 South Flank of Kilauea earthquake shook the Big Island of Hawaii, Hawaii. The Kilauea volcano sent more lava into Hawaii communities Friday, a day after forcing more than 1,500 people to flee from their mountainside homes, and authorities detected high levels of sulfur gas that could threaten the elderly and people with breathing problems.
