Summit overflight shows Halema‘uma‘u growth

Mid-day overflight on June 5 shows ongoing partial collapse of Halema'uma'u Crater at the summit of Kīlauea Volcano. To the north of the old 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. The summit is still subsiding due to withdrawal of magma towards the East Rift Zone.
