31 episodes of lava fountaining at the summit of Kīlauea since December 23, 2024, have covered the floor of Halemaʻumaʻu with a patchwork of lava flows of varying ages. With each episode, more of the crater floor is covered and in total, the lava flows have filled over 260 feet (80 meters) of the crater with new lava.  USGS photo by M. Patrick.

On the south rim of Halemaʻumaʻu, new sink holes in ash and tephra that blankets the ground in this area were observed following episode 30 of the Kīlauea summit eruption on August 6. The sinkholes formed due to underlying cracks that opened as a result of the new fissure in the south wall of the caldera. USGS photo by M. Patrick.
