Kīlauea summit eruption reference map — September 14, 2023
The Kīlauea summit eruption that began on Sunday, September 10, 2023 continues; this map depicts lava flow activity as of September 14, the fourth full day of the eruption. Lava is erupting from multiple fissures on the eastern down-dropped block from the 2018 caldera collapse, having inundated both the block itself and sections of the western floor of Halema‘uma‘u crater. The western floor was built during the previous four eruptions in Halema‘uma‘u dating back to 2020, with the extent of lava from the June 2023 eruption marked in purple. Approximately 496 acres (201 hectares) have been covered with new lava since Sunday, with active flows still covering approximately 108 acres (44 hectares).
