Kīlauea Volcano's summit

The Unmanned Aircraft Systems (UAS) team circumnavigates the crater rim at the summit of Kīlauea Volcano, collecting data for digital elevation models that document summit changes. The volume change, from early May 2018 to present, is over 825 million cubic meters (1 billion cubic yards). The vertical collapse of the crater floor is more than 500 m (1600 ft). Limited UAS flights into this hazardous area are conducted with permission and coordination with Hawai‘i Volcanoes National Park. Scientists examine the UAS data in detail to understand how the collapse area is evolving and to assess hazards at Kīlauea's summit, all of which is shared with the National Park Service and emergency managers.
