June 7, 2023
map showing eruptive activity of June 7, 2023
A new eruption at the summit of Kīlauea volcano began at approximately 4:43 a.m. on Wednesday, June 7, 2023. This reference map depicts activity in the first two hours of the eruption, based on measurements taken from the crater rim at approximately 6:00 a.m. Multiple eruptive vents on the floor of Halema‘uma‘u crater are effusing directly into a lava lake that sits atop them, with the vents taking the form of dome fountains. Lava from these dome fountains—which are marked in orange—is flowing laterally across the rest of the crater floor. The extent of the newly erupted lava—the area in red—is 371 acres (150 hectares). A handful of small islands from previous Kīlauea summit eruptions remain exposed and are marked in yellow.
