A small explosive eruption occurred at Halemaumau crater at 12:55 a.m., according to the Hawaiian Volcano Observatory.
The resulting ash plume reached a height of 7,000 feet and was blown to the southwest by the prevailing winds. The communities of Wood Valley, Pahala, Naalehu and Waiohinu are advised that ash could be blown their way, according to the Hawaii County Civil Defense.
