KWcam image taken on Sept. 27, 2022. The floor of Halemaʻumaʻu has grown in area and elevation due to the ongoing eruption in crater. The island that formed on Dec. 20, 2020, is surrounded by younger lava flows so what is seen on the surface of Halemaʻumaʻu crater floor today represents the oldest and youngest deposits from these recent eruptions!
KWcam image taken on Sept. 28, 2021, before the eruption began in Halemaʻumaʻu on Sept. 29, 2021. Several islands, including the one in the center of the crater that formed on Dec. 20, 2020, are surrounded by younger lava flows erupted during the December 2020-May 2021 Kilauea summit eruption.
Crater filling at Kilauea is sometimes like pouring liquid into a mug, but more often it is like injecting haupia crème into a crispy malasada.
