This photo shows the southern portion of Kīlauea Caldera, and was taken from the water pond observation area on the west caldera rim. The photo gives a sense of the scale of the 2018 collapse. A portion of Crater Rim Drive is present on the lower block, which was originally level with the remainder of Crater Rim Drive visible at the top of the photo. This section of the road dropped approximately 80 meters (260 feet), but other parts of the caldera floor dropped more than 500 meters (1600 feet). The scarp formed during the 2018 collapse sequence. Most of the large Halema‘uma‘u parking lot disintegrated during the 2018 collapses, but a tiny portion remains at the base of the talus slope. USGS photo by M. Patrick.
