Kilauea summit crater after collapse in 2018

This is a view of the summit area from the southwest, showing the collapsed area of Halema‘uma‘u and the adjacent caldera floor. A section of Crater Rim Drive preserved on a down-dropped block is visible at the far right. Volcanic gases rising from magma stored beneath the summit continue to escape to the surface, as they have for as long as Kīlauea has existed, resulting in deposits of sulfur on the crater walls.
