Kīlauea summit eruption - Dec. 30, 2020, at 5 a.m. HST

HVO field crews observed activity within Halema‘uma‘u, at Kīlauea Volcano's summit, overnight from within a closed area of Hawai‘i Volcanoes National Park. The area remains closed to the public for safety reasons and HVO field crews are equipped with a range of specialized safety gear and personal protective equipment. In the early hours of December 30, the western vent in the wall of Halema‘uma‘u continued to erupt primarily effusively (flowing lava), but sporadic strombolian activity (minor explosions ejecting lava into the air) was also observed at the top of the west vent.
