Kīlauea Summit UAS footage shows an ever growing Halema‘uma‘u

A UAS mission on June 24, 2018, filmed details of the dramatic changes occurring within Halema‘uma‘u crater at Kīlauea's summit since explosive eruptions of ash and gas and ongoing wall collapse began in mid-May. Clearly visible are the steep crater walls that continue to slump inward and downward with ongoing subsidence at Kīlauea's summit. The deepest part of Halema‘uma‘

Kīlauea Volcano — Remobilized Ash Plume

Recent explosive events haven't produced significant ash plumes from the summit, but downwind communities may still experience ashfall when previously erupted ash is remobilized. On authorized permission from Hawai‘i Volcanoes National Park, our Unmanned Aircraft Systems crew is conducting gas measurements at Pu‘u ‘Ō‘ō. They snapped this photograph from Chain of Craters
