HVO's mid-day overflight on June 5 shows ongoing partial collapse of Halema‘uma‘u at the summit of Kīlauea Volcano. To the north of the former visitor Overlook parking area (closed in 2008) is the site of the former lava
lake—now a deep hole piled with wall-rock rubble. The western portion of Halema‘uma‘u has moved down and toward the center of the crater as new cracks form on the caldera
floor to the west. Kīlauea's summit continues to subside due to withdrawal of magma
towards the volcano's East Rift Zone.
