An eruption at Kīlauea's summit began at approximately 3:20 p.m. HST on September 29, 2021. Intermittent 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.

This 8 meter (26 feet) tall arch of lava was left behind during a lull in eruptive activity within Halema‘uma‘u crater, at Kīlauea's summit. This feature is located in the spillway that connects the vent of Halema‘uma‘u to the lava lake. HVO field crews note that there was no lava actively flowing through the spillway, although there were several re-surfacing events that occurred on the stagnant lake surface. USGS photo by L.

A small bridge of lava 3 meters (10 feet) in height is left behind during a lull in activity within Halema‘uma‘u crater at Kīlauea's summit. The repeated ebb and flow of lava into the active lake surface has caused the pond behind this feature to start pinching off from the main part of the active lake that fills with lava when activity is more vigorous. This telephoto picture was taken from the western rim of Halema‘uma‘u. USGS photo by L. Gallant.
