Kīlauea Volcano —

Comparison of photographs taken on June 13 and 26 from near Keanakāko'i Crater overlook in Hawai'i Volcanoes National Park shows a subsidence scarp that formed as the Kīlauea Crater floor subsided. Scientists estimate the dramatic dropping of the crater floor in this area occurred sometime between June 23 and 26. The view is to the west. Halema‘uma‘u crater is in upper

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‘
