Kīlauea volcano is erupting. With the summit eruption continuing through the night, HVO scientists monitor the eruption for changes in activity and volcanic hazards. High levels of volcanic gases are the primary hazard of concern, as this hazard can have far-reaching effects down-wind. USGS photo taken by D. Downs.

This image from the northwest rim of Halema'uma'u crater was taken in the late morning on September 29, 2021, just a few hours before the new Kīlauea summit eruption began. The solidified lava lake (center) was emplaced between December 2020 and May 2021. USGS photo taken by L. Gallant.

A telephoto image of fissures that opened on the western wall of Halema'uma'u crater during the ongoing eruption that began yesterday, September 29, at approximately 3:21 p.m. HST. Lava from multiple fissures continues to slowly raise the level of the new active lava lake at the summit of Kīlauea. USGS image by M. Patrick.

Kīlauea volcano is erupting. At approximately 3:20 p.m. HST on September 29, 2021, an eruption began within Halemaʻumaʻu crater in Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park. Fissures at the base of Halemaʻumaʻu crater are generating lava flows on the surface of the lava lake that was active until May 2021.

The new eruption within Halema‘uma‘u crater at Kīlauea's summit is depositing tephra downwind of the erupting vents. Tephra is a term that describes products of an eruption that travel through the air before being deposited.

Hawaiian Volcano Observatory geologists collect tephra samples from the recent eruption within Halema'uma'u, at Kīlauea summit. Geochemical analyses of these eruption products will provide information about magma storage prior to the eruption. USGS image by K. Lynn.

This reference map depicts the ongoing Kīlauea summit eruption as of approximately 6:00 PM on September 29, 2021. Several new fissures (orange lines) within Halema‘uma‘u have erupted enough lava (red) to cover nearly all of the 12/2021–5/2021 lava lake by more than 36 ft (11 m).

This timelapse image sequence shows the opening sequence of the new eruption in Halema‘uma‘u crater, at the summit of Kīlauea. The first few moments are shown on a loop several times to highlight the visible uplift of the crater floor, just before the appearance of new fissures.
