Detailed Description

This series of images from June 13 through July 7, 2018, show the dramatic down-dropping of Kīlauea Volcano's summit caldera floor. For weeks, the summit has subsided both in a continuous fashion and in incremental and jolting drops. The withdrawal of magma towards the East Rift Zone continually works to reduce pressure in the shallow magma reservoir. When the reduction in pressure becomes too great, the rock that forms the floor of Halema‘uma‘u and parts of surrounding Kīlauea Caldera slump down into the shallow magma reservoir to generate a collapse/explosion event. These events occur about every 28 hours. This view, from the Keanakāko‘i Overlook, is toward the north, across the caldera floor.
