The Unmanned Aircraft Systems (UAS) team completed its mission at Kīlauea Volcano's summit, mapping changes within the caldera. Since August 4, 2018, the number of earthquakes at the summit have decreased and the rate of subsidence has stabilized. Sulfur dioxide (SO2) emission rates at the summit is less than 200 tonnes/day, which is lower than at any time since late 2007. 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.
