For the first time since 1984, the Mokuʻāweoweo Caldera of the Mauna Loa volcano located in Hawai‘i Volcanoes National Park began erupting at 1130 HST on 27 November. The lava flow is currently contained with the Mokuʻāweoweo Caldera, located at the summit of Mauna Loa. The USGS advises lava flows are visible from Kona. The Hawai‘i Volcanoes National Park has closed the Mauna Loa summit area to visitors.
Air Travel to the Big Island
Air travel to the island of Hawaii is unaffected at this time, save for the exclusion zone above the erupting volcano.
Kīlauea
Separately, the eruption at Kīlauea volcano which began on September 29, 2021, at approximately 3:21 p.m. HST in Halema‘uma‘u crater continues and has generated an large lava lake, and visitors to the National Park have been able to observe Kilauea from the rim of that caldera.
Mokuʻāweoweo Caldera
No evacuation order has been given at this time. That said, the County of Hawaii issued an emergency notice as residents on the south end of the Big Island of Hawaii began self-evacuating.
Though the USGS Volcano Observatory believes the current eruption will remain within the caldera, should lava begin to vent and flow outside the caldera, the situation could change rapidly.
The County’s website includes an Mauna Loa Inundation Zones interactive map which is searchable by address.
