West vent and Halema‘uma‘u lava lake
The eruption within Halema‘uma‘u crater, at the summit of Kīlauea, continues to feed a rising lava lake. During the evening of December 15, 2021 a period of increased eruptive activity included lava entering the lake from multiple sources and frequent large spatter bursts throwing lava onto the sides of the west vent cone.
