A photogrammetry survey of Kīlauea's summit by the U.S. Department of Interior Unmanned Aircraft Systems' (UAS) Kīlauea response team show changes that have occurred at Halema‘uma‘u as of June 8. Cracks through the former overlook parking lot (bottom of image) wrap around the east margin of Halema‘uma‘u and extend to the north. New faulting and slumping apparent on west side of the crater, with cracks that extend farther to the northeast. Halema‘uma‘u has grown in size since early May, with a diameter now estimated to be 1.8 km (1.1 mi), compared to 1 km prior to recent events. Although the exact crater boundary is difficult to define in places. Limited UAS flights into area are conducted with permission and coordination with Hawai‘i Volcanoes National Park to provide hazard assessments and to collect quantitative and qualitative data, all of which is shared with emergency managers.
