Lava lake level measurements collected during a field visit of Kīlauea Volcano's summit just after 11:44 a.m. HST on December 23, 2020, were used to create a preliminary lava lake depth map. When compared to pre-eruption topographic models, it shows that the bottom of Halema'uma'u crater has been filled by almost 158 m (yd) of lava. Mapping indicates that the lake is approximately 27.5 hectares (68 acres) in size. Both fissures are indicated by yellow triangles on the map. Map by H. Dietterich.
