PAHOA, HI - MAY 4: In this handout photo provided by the U.S. Geological Survey, a column of robust, reddish-brown ash plume occurred after a magnitude 6.9 South Flank following the eruption of Hawaii's Kilauea volcano on May 4, 2018 in the Leilani Estates subdivision near Pahoa, Hawaii. The governor of Hawaii has declared a local state of emergency near the Mount Kilauea volcano after it erupted following a 5.0-magnitude earthquake, forcing the evacuation of nearly 1,700 residents.
