The September 23, 2020, overflight provided aerial photos of Kīlauea's summit that were used to construct an updated map. Poor weather prevented full coverage of the caldera floor, and this map is focused on Halema‘uma‘u. The water lake was 300 m (980 ft) long and had a surface area of 3.3 hectares (8.2 acres). For comparison, on May 29, 2020, the lake was approximately 2.5 hectares (6.2 acres). The label "downdropped block" shows one of the large portions of the caldera floor that subsided, along with the Halema‘uma‘u region, during the 2018 eruption.
