A wide view of the lava lake within Halema‘uma‘u crater at Kīlauea summit, taken on March 24, 2021 at 12:48 p.m. HST. A gas plume rises from the west vent (center-left), which continues to erupt lava into the active western portion of the lava lake (light gray in color). The center and eastern lava lake surface is covered by a darker, stagnant crust.

The lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, remains active. Active surface lava is limited to the western (bottom) portion of the lake between the main island and the western fissure complex. In this view looking east, a 4 meter (13 feet) diameter skylight is visible at the top of the northeastern-most spatter cone (left). USGS photo by N.

Crustal foundering—less-dense liquid lava overriding and sinking thin surface crust—is common in the lava lake within Halema‘uma‘u, at the summit of Kīlauea. Here, large sections of the crust are foundering, resurfacing the lake. USGS photo by M. Patrick on March 22, 2021.
