June 24, 2026 — Eastern margin of Halemaʻumaʻu, Kīlauea summit

At the eastern margin of Halemaʻumaʻu, where the episodic lava fountaining eruption has been taking place since December 2024, lava flows have encroached on nearly the entire surface of the "down-dropped block." This feature lowered during the 2018 collapse and while most of its surface has been covered with new lava flows, much of the volume of the 2018 collapse remains to be filled with lava flows.
