A new eruption at Kīlauea's summit began at approximately 3:20 p.m. HST on September 29, 2021. Lava activity is currently 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.

A telephoto view of the flow on the south side of the west vent cone within Halema‘uma‘u crater, at the summit of Kīlauea. The direction of flow is from the west (bottom) to the east (top). Entrained pieces of solidified crust (black) can be seen in the flow and can be used to determine the direction of flow. Photo taken from the western rim on November 15, 2021, at 12:52 p.m. HST.
