HONOLULU<\/strong> \u2014 At about 11:30 p.m. HST on Sunday, Nov. 27, 2022, Mauna Loa volcano on the Big Island of Hawai\u2018i began erupting.<\/p>\n\n\n\n At this time, the lava is confined to the immediate area of the mountain\u2019s summit, and has not begun flowing outside that area. No communities downslope from the caldera are immediately threatened, and about half of all recorded Mauna Loa eruptions have been confined to the summit area.<\/p>\n\n\n\n The United States Geological Survey\u2019s Hawaiian Volcano Observatory (HVO) has increased the alert level for volcanic activity on Mauna Loa from \u201cadvisory\u201d to \u201cwarning\u201d with the start of eruption. The volcano has been exhibiting increased seismic activity since September, which prompted scientists to increase monitoring and begin public outreach on the Big Island.<\/p>\n\n\n\n HVO also increased the aviation threat level from \u201cyellow\u201d to \u201cred\u201d to reflect the presence of airborne gases, ash particles and possibly \u201cPele\u2019s hair\u201d volcanic glass fibers. The volcanic particles also prompted the National Weather Service to issue an Ashfall Advisory for the Big Island through 6 a.m. Monday, with a quarter-inch of ash accumulation possible. People with respiratory problems should stay indoors or wear masks or cloths to limit exposure to the particles.<\/p>\n\n\n\n The Hawai\u2018i Emergency Management Agency (HI-EMA) has activated its Emergency Operations Center for enhanced monitoring of the evolving situation and provide any support requested. We are in close communication with Hawai\u2018I County Civil Defense Agency (HCCDA) and HVO, and will provide additional information as the situation evolves. At this time, no evacuation has been ordered.<\/p>\n\n\n\n
