The US Geological Survey (USGS) said aerial footage recorded on June 24 shows the dramatic changes occurring within the Halema‘uma‘u crater at Hawaii’s Kilauea’s volcano since eruptions began in May.The USGS said the crater walls seen in this footage will continue to slump inward and downward with ongoing subsidence at Kilauea’s summit. The deepest part of the crater was measured at 1300 ft below the caldera floor, the agency said. Credit: USGS via Storyful
