December 22, 2020—Kīlauea summit eruption lava lake depth map

Color map showing lava lake thickness

Detailed Description

Aerial visual imagery collected during an overflight of Kīlauea Volcano's summit just after 11:30 a.m. HST on December 22, 2020, was used to create a preliminary topographic model. When compared to pre-eruption topographic models, it shows that the bottom of Halema'uma'u crater has been filled by almost 150 m (yd) of lava. Mapping indicates that the more vigorous north fissure is 50-55 meters (yards) wide whereas the west fissure is 20 meters (yards) wide at most (both fissures indicated by red lines on map). Map by B. Carr.
