View of lava lake in Halema‘uma‘u - Kīlauea, March 15, 2021

View of the lava lake from the south rim of Halema‘uma‘u, at the summit of Kīlauea, looking north. The western (left) portion of the lava lake remains active, with small scale crustal foundering events. Lava enters the lake at two sources approximately 20 to 30 meters (65 to 100 ft) apart at the base of the western vent spatter cone. The western active lava lake has been getting progressively smaller over the past several weeks, and is now confined to the area west of the main island. The stagnant eastern portion of the lake (right) is about 5 meters (16 ft) lower than the active western portion. USGS photo taken by N. Deligne on March 15, 2021.
