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.

Lava erupting from the west vent within Halema‘uma‘u crater, at Kīlauea summit. Frequent large spatter bursts were observed at the west vent during a period of increased eruptive activity that lasted for a few hours on the evening of December 15, 2021. This photo was taken from the public viewpoint near Keanakāko‘i crater in Hawai‘i Volcanoes National Park.

A view of the western part of the lava lake within Halema‘uma‘u crater, at the summit of Kīlauea. Lava effusion from the west vent (lower left) had significantly decreased during the time of this photo. The western part of the lava lake surface was crusted over and had developed a noticeable topography, with islands perched within the lava lake.

A view of the lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, on Monday, December 13, 2021. Very little eruptive activity had been observed during the previous day at the summit. Over the past week, the lake level has continued to rise and covered more of the lowest down-dropped block (center left).

The eruption in Halema'uma'u crater, at the summit of Kīlauea, continues.
