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.

July 8, 2022 — Kīlauea summit eruption continues

The eruption within Halema‘uma‘u crater, at the summit of Kīlauea, continues. The lava level in the active lake, pictured here on July 8, dropped by several meters (yards) yesterday in association with summit deflation. USGS photo by K. Mulliken.
Color photograph of lava lake
Minor spattering was visible in the east end of the lava lake within Halema‘uma‘u, at the summit of Kīlauea, on July 8. Sulfur dioxide is visible emanating from the lake surface (the bluish-colored fume). A sulfur dioxide emission rate of approximately 2,800 tonnes per day (t/d) was measured on July 8.

Fragments of spatter are visible above the west vent in Halema‘uma‘u in this telephoto image taken during a Kīlauea summit eruption monitoring shift on July 8. This low-level spattering, which was intermittent, reached heights of no more than 10 meters (33 feet) above the vent. USGS photo by M. Loewen.

This photo shows the east end of Halema‘uma‘u crater, where the rising crater floor is lapping on to the sloped edge of the down-dropped block to the east. The down-dropped block formed during the collapse of Kīlauea summit in 2018. USGS photo by M. Loewen.
Color photograph of hornito
Telephoto image of a degassing hornito on the surface of the eastern part of Halema‘uma‘u crater floor. Halema‘uma‘u crater floor has several hornitos on its surface; each is several tens of feet tall (less than 30 meters) and is fed lava via a tube network beneath the solid surface crust. USGS photo by M. Loewen.

A telephoto view of the island that formed during the December 20, 2020, eruption within Halema‘uma‘u crater at the summit of Kīlauea. The island has been slowly shrinking as lava flows encroach around and onto it. In the background, the line of steam marks where the rising floor of Halema‘uma‘u is lapping on to the down-dropped block to the northeast. USGS photo by M. Loewen.
Color photograph of scientists in field
From the south rim of Halema‘uma‘u crater, USGS scientists make observations of the eruption at Kīlauea summit. The western edge of Halema‘uma‘u crater floor is visible in the lower right part of the image, as is a section of Crater Rim Drive that collapsed in 2018. Mauna Loa is prominent in the background of the photo. USGS photo by K. Mulliken.
