A summit eruption of Kīlauea volcano, within Halemaʻumaʻu crater, began at approximately 4:44 a.m. on June 7, 2023. Lava is flowing on the crater floor and there are several active vent sources. The eruption at Kīlauea’s summit is occurring within a closed area of Hawai'i Volcanoes National Park and high levels of volcanic gas are the primary hazard of concern.
