The eruption in Halema‘uma‘u crater continues. The eruption, which is occurring inside the Kīlauea summit caldera within Hawai‘i Volcanoes National Park, began the morning of June 7, 2023.

Hawaiian Volcano Observatory scientists collect detailed data to assess hazards and understand how the eruption is evolving at Kīlauea's summit, all of which are shared with the National Park Service and emergency managers. Access to this hazardous area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park. The eruption is occurring within Halemaʻumaʻu, a location that is significant to Native Hawaiian communities because it is the home of the deity Pele.

View from the southern rim of Halemaʻumaʻu crater at the summit of Kīlauea on Friday, June 16, 2023, showing the southwest eruptive vent that is currently spattering and feeding lava flows on the crater floor. The fountaining is continuous, with lava bombs being thrown at least 10 m (33 ft) upwards and at least twice that distance away from the vent. USGS photo by D. Downs.

The eruptive vent in the southwest wall of the crater (right) appeared to be the only active vent, and it was supplying lava into a lake in the southwestern portion of the crater. USGS photo by M. Patrick.
