Kīlauea summit eruption on May 25, 2021

An overview of the lava lake within Halema‘uma‘u crater, at Kīlauea Volcano’s summit, taken on May 25. Kīlauea’s summit collapse in 2018 deepened Halema‘uma‘u crater by over 500 meters (1640 feet). The eruption that began the evening of December 20, 2020, has filled approximately 229 m (751 ft) of the base of Halema‘uma‘u crater, which is more than the height of the Space Needle in Seattle, Washington.
