MEDIA RELEASE

U.S. Geological Survey: At approximately 11:30 p.m. HST this evening, November 27, an eruption began in Moku‘āweoweo, the summit caldera of Mauna Loa, inside Hawai‘i Volcanoes National Park. At this time, lava flows are contained within the summit area and are not threatening downslope communities.  Winds may carry volcanic gas and possibly fine ash and Pele’s hair downwind.

Residents at risk from Mauna Loa lava flows should review preparedness and refer to Hawai‘i County Civil Defense information for further guidance. 

Based on past events, the early stages of a Mauna Loa eruption can be very dynamic and the location and advance of lava flows can change rapidly.    

If the eruption remains in Moku‘āweoweo, lava flows will most likely be confined within the caldera walls.  However, if the eruptive vents migrate outside its walls, lava flows may move rapidly downslope.   

HVO is in close consultation with emergency management partners and will be monitoring the volcano closely to provide further updates on activity.  As soon as possible, HVO will conduct aerial reconnaissance to better describe the eruption and assess hazards.
