Kīlauea summit eruption in Halemaʻumaʻu crater - September 30, 2021

This overview photo of the lava lake within Halema‘uma‘u was captured from the west rim of the crater shortly after noon on September 30, 2021. Several fissures, erupting through the lava lake, stretch from the lake's center to its southern (right) margin. Another fissure erupts in the western wall of Halema‘uma‘u (near side) just several meters (yards) above the lake surface. Three features from the December 2020–May 2021 eruption remain visible: the western fissure (darker spot on near side), the main island (center), and another smaller island in the eastern part of the lake (upper left).
