May 29, 2020—Updated aerial map of Kīlauea summit

Color orthomosaic of Kīlauea  volcano summit

Detailed Description

The May 29 overflight provided updated aerial photographs of Kīlauea summit, covering the caldera floor and showing the current size of the water lake in Halema‘uma‘u crater. The water lake has a surface area of approximately 25,000 square meters (6.2 acres), which is more than double the area measured in late December, when it was 11,000 square meters (2.7 acres). The water lake is still smaller in area than the former Halema‘uma‘u lava lake, which was approximately 48,000 square meters (11.9 acres) just before it drained in May 2018. The label "downdropped block" shows the large portion of the caldera floor that subsided, along with the Halema‘uma‘u region, during the 2018 eruption. The surrounding area is shown by a 2018 satellite image.
