Halemaumau is forever changed. The Lava Lake has disappeared.

UAS survey of Halema‘uma‘u crater rim, at Kīlauea Volcano’s summit, June 13, 2018.

A UAS mission on June 13, 2018, filmed details of the dramatic changes occurring within Halema’uma’u crater at Kīlauea's summit. Clearly visible are the steep crater walls that continue to slump inward and downward in response to the ongoing subsidence at the summit. The deepest part of Halema‘uma‘u is now about 300 m (1,000 ft) below the crater rim.This video was taken from a UAS (Unmanned Aircraft Systems). Limited UAS flights into this hazardous area are conducted with permission and coordination with Hawai'i Volcanoes National Park. The overflights collect visual information on what is happening at this rapidly changing eruption site. Scientists will be examining the footage in detail to understand how the expanding collapse area is evolving, the extent of tephra fall, and other clues as to what is happening at Kīlauea's summit. This information informs assessment of hazards, which is shared with the National Park Service and emergency managers.Video by the U.S. Geological Survey and Office of Aviation Services, Department of the Interior, with support from the Hawaiian Volcano Observatory and Hawai'i Volcanoes National Park.#usgs #hvo #hawaiianvolcanoobservatory #kilauea #volcano #KilaueaErupts #LERZeruption #LERZ #KilaueaEruption
