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.

A 1-meter (3-foot)-high standing wave was present in the spillway that is feeding the active portion of Kīlauea's summit lava lake, as seen from the west side of Halema‘uma‘u crater (in the vicinity of the KWcam and looking to the east). USGS photo by L. Gallant

Small overflows from the pond feeding the eruption in Halema‘uma‘u

This view of the western vent in Halema‘uma‘u was captured on February 10, 2022. The pond north of the west vent generally feeds the active part of the lava lake at the summit of Kīlauea volcano through the spillway seen on the top right of the photograph. Small increases in effusion rate can cause the pond to overflow, sending lava to the west, seen here in the foreground. USGS photo by L. Gallant.
