During the morning of September 11, Hawaiian Volcano Observatory geologists conducted an overflight of the new eruption within Kīlauea summit caldera. The eruption is occurring in the east portion of Halemaʻumaʻu crater and on the downdropped block to the east, which formed during the 2018 summit collapse.

Frequently Asked Questions about Kīlauea's Summit Eruption
How long did the eruption last? How deep is the crater? And more...
Kīlauea was erupting at the summit most recently from September 10-16, 2023. Several roughly east-west oriented vents on the western side of the downdropped block within Kīlauea's summit caldera generated lava flows onto Halema‘uma‘u crater floor, within Hawai‘i Volcanoes National Park.
- Sunday, September 17, 2023, 9:30 AM HST: The Kīlauea summit eruption that began on September 10th stopped yesterday, September 16th, and is unlikely to restart.
- Yesterday morning, HVO field crews reported that active lava was no longer flowing onto Halemaʻumaʻu crater floor and was restricted to a ponded area north of the vents on the downdropped block. They observed lava spattering at the vents cease at approximately 11:15 am September 16.
- Overnight webcam views showed some incandescence across the eruption area as lava erupted over the past week continues to cool.
- Field observations are supported by geophysical data, which show that eruptive tremor (a signal associated with fluid movement) in the summit region decreased over September 15 and 16 and returned to pre-eruption levels by 5 p.m. HST on September 16.
- Saturday, September 16, 2023, 9:30 AM HST: Field crews observed eruptive activity greatly decrease or cease.
- Webcam imagery shows little or no fountaining since 7 a.m., however, intermittent spattering was seen from the westernmost large cone throughout the night.
- Webcam imagery over the past day shows that the area of active lava has retreated even further towards the vents though numerous oozeouts of lava were visible over other parts of Halema‘uma‘u crater floor overnight.
- The laser rangefinder recorded little change over the past 24 hours.
- A sulfur dioxide (SO2) emission rate was not measured since September 13.
- Friday, September 15, 2023, 9:30 AM HST: Several vents continue to erupt. Effusion rates continue to decrease, but remain significant.
- Vigorous spattering is restricted to the westernmost large spatter cone with fountains 10-15 meters (32-50 feet).
- Pāhoehoe lava flows continue to travel in north and west directions from the vents and onto Halema‘uma‘u crater floor.
- The laser rangefinder recorded about 10 meters (33 feet) of uplift to the western part of Halema‘uma‘u since the eruption started.
- A sulfur dioxide (SO2) emission rate was not measured since September 13.
- Thursday, September 14, 2023, 9:30 AM HST: Vents continue to erupt on the western side of the downdropped block within Kīlauea's summit caldera and are generating lava flows onto Halema‘uma‘u crater floor. Effusion rates appear down from initial eruptive rates, but remain high.
- Lava fountain heights reach up to about 10 meters (32 feet).
- Pāhoehoe lava flows continue to travel in north and west directions onto Halema‘uma‘u crater floor; however, the area of active lava has retreated even further towards the vents compared to days prior.
- The laser rangefinder has recorded nearly 9 meters (30 feet) of endogenous uplift of the western portion of Halema‘uma‘u. This demonstrates that a significant amount of lava has intruded beneath the pre-existing crust within Halema‘uma‘u.
- A sulfur dioxide (SO2) emission rate of 20,000 tonnes per day was measured yesterday afternoon, September 13.
- Wednesday, September 13, 2023, 9:30 AM HST: East-west trending vents, spanning approximately 0.5 miles (750 m), continue to erupt on the western side of the downdropped block within Kīlauea's summit caldera. Effusion rates appear down from initial eruptive rates, but remain high.
- Lava fountain heights have decreased since the eruption onset, but remain up to about 10 meters (32 feet) high.
- Pāhoehoe lava flows continue to travel in north and west directions onto Halema‘uma‘u crater floor; however, the area of active lava has retreated towards the vents compared to yesterday. The area north of the eruptive vents has become perched and is about 3 meters (15 feet) higher than the surrounding ground surface.
- The laser rangefinder, aimed at a western portion of Halema‘uma‘u, not near the new eruptive activity, recorded nearly 6 m (20 feet) of uplift to this locality since the eruption started. This demonstrates that a significant amount of lava has intruded beneath the pre-existing crust within Halema‘uma‘u.
- A sulfur dioxide (SO2) emission rate of 30,000 tonnes per day was measured yesterday morning, September 12.
- Tuesday, September 12, 2023, 9:30 AM HST - Several roughly east-west trending lava fountains remain active on the western side of the downdropped block within Kīlauea's summit caldera. The easternmost vents on the downdropped block and the westernmost vents in Halema‘uma‘u became inactive yesterday, and the remaining active vents on the downdropped block span approximately 0.5 miles (750 m). Effusion rates appear down from initial eruptive rates, but remain high.
- Lava fountain heights have decreased since the eruption onset, but remain up to about 10-15 meters (32-50 feet) high.
- The vents are feeding channelized lava flows traveling in north and west directions onto Halema‘uma‘u crater floor. The eastern rim of Halema‘uma‘u crater has been buried by new lava flows, and pāhoehoe lava flows cover most of the crater floor except high ground formed during previous eruptive activity in the southwest portions of the crater.
- The laser rangefinder is aimed at a western portion of Halema‘uma‘u crater, not near the new eruptive activity, and recorded nearly 5 m (16 feet) of uplift to this locality since the eruption started. This demonstrates that a significant amount of lava has intruded beneath the pre-existing crust within Halema'uma'u. Volcanic gas emissions in the eruption area are elevated;
- A sulfur dioxide (SO2) emission rate of 49,000 tonnes per day was measured yesterday afternoon, September 11.
- Monday, September 11, 2023, 8:55 AM HST - Multiple minor fountains remain active in a line of vents stretching approximately 0.8 miles (1.4 km), from the eastern part of Halema‘uma‘u crater floor extending into the east wall of the downdropped block. Effusion rates appear down from initial eruptive rate, but remain high.
- Lava fountain heights have decreased since the eruption onset, but remain up to about 10-15 meters (32-50 feet) high.
- Lava erupted from fissures on the downdropped block is flowing in a westward direction towards Halema‘uma‘u crater, covering much of the surface with active lava.
- The laser rangefinder is aimed at a western portion of Halema‘uma‘u crater, not near the new eruptive activity, and recorded about 2.5 m (8 feet) of rise to that part of the crater floor.
- Preliminary sulfur dioxide (SO2) emission rates of up to 100,000 tonnes per day or more were measured between 4 and 5 p.m. yesterday.
- Sunday, September 10, 2023, 3:18 PM HST - Kīlauea summit begins erupting at approximately 3:15 p.m. HST. Vents erupt on the down dropped block to the east of Halemaʻumaʻu crater, and in the crater, within Kīlauea’s summit caldera, within Hawai‘i Volcanoes National Park. The eruption was preceded by a period of strong seismicity and rapid uplift of the summit.

Kīlauea started erupting on September 10, 2023, at approximately 3:15 p.m. H.S.T., from fissures which extended from the eastern margin of Halema‘uma‘u crater and onto the down-dropped block to the east within Kīlauea’s summit caldera.

Another eruption at the summit of Kīlauea volcano began at 3:13 p.m. on September 10, 2023. This video, captured by the Hawaiian Volcano Observatory's B2cam on the east rim of Halemaʻumaʻu crater, shows the opening phase of the eruption. A lava fountain bursts from a degassing area in the eastern portion of Halemaʻumaʻu crater.

The B1cam, located on the east margin of the down-dropped block within Kīlauea caldera, captured the start of another eruption at the summit of Kīlauea volcano that began at 3:13 p.m. on September 10, 2023. This video shows a lava fountain bursting from a degassing area in the eastern portion of Halemaʻumaʻu crater, with the downdropped block in the foreground.

From the Uēkahuna overlook, the new eruption at the summit of Kīlauea is visible. The farthest east fissure is near the to margin of downdropped block that formed during the 2018 summit collapse. The base of the main fissure, which is farthest west (right on the image), is approximately 70 meters wide.
