March 29, 2021 — Kīlauea
The lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, remains active. The active surface lava lake, shown in this photo, is limited to the western portion of the lake between the western fissure complex (center left) and the main island (right). In this view looking to the northwest, the main effusion source of lava into the lake is visible as a saw-tooth line at the northeastern (right) base of the western fissure complex. Small scale crustal foundering events continue within the active lava lake. USGS photo by N. Deligne on March 29, 2021.
