VIDEO: Kilauea volcano summit overflight shows the expansion of Halema‘uma‘u crater

Hawaiian Volcano Observatory’s midday overflight on June 5, 2018, shows ongoing partial collapse of Halema‘uma‘u at the summit of Kilauea volcano in Hawaii Volcanoes National Park on the Big Island of Hawaii.

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. Kilauea’s summit continues to subside due to withdrawal of magma towards the volcano’s East Rift Zone.
