An eruption at Kīlauea's summit began at approximately 3:20 p.m. HST on September 29, 2021. Lava activity is confined within Halema‘uma‘u crater, in the closed area of Hawai‘i Volcanoes National Park.

HVO scientists collect detailed data to assess hazards and understand how the eruption is evolving at Kīlauea's summit, all of which are shared with the National Park Service and emergency managers. Access to this hazardous area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park.

Thermal camera timelapse of Kīlauea summit lava lake growth

This timelapse sequence shows the evolution of the lava lake and rise of the crater floor in Halema‘uma‘u, at the summit of Kīlauea Volcano, since the eruption start in September 2021. Much of the the crater floor rise is driven by lava supplied beneath the surface crust. The camera is located on the west rim of the summit caldera, looking east. The sequence is shown three times.
