View of active portion of lava lake in Halema‘uma‘u - Kīlauea, Feb. 23

The lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, remains active. Active surface lava remains limited to the western portion of the lake, shown here as seen from the south rim of the crater and looking towards the northwest. The western fissure cone is in the center of the photo. The top of the main cone is obscured by volcanic gases, and a small glow area is visible at the tip of a vent slightly north (right) of the main cone. Lava enters the lake at the base of the western fissure cone in incandescent area. USGS photo by N. Deligne.
