A telephoto image of the west vent within Halema‘uma‘u crater, at the summit of Kīlauea. The west vent lava fountain remains active with sustained heights of 10–15 meters (33–49 ft). The fountain continues to build a spatter cone around it, but is mostly out of view from this vantage point on the western crater rim. USGS photo taken by D.

A telephoto image of the southern lava fountain from the south rim of Halema‘uma‘u at Kīlauea summit. This view shows most of the fissure vent that is located within the south-central part of the lava lake. The fissure is about 35 m long and has sustained low fountains heights of up to 5 meters (16 ft), with some bursts reaching up to 10 meters (33 ft) high.

A telephoto view of the lava fountain in the western wall of Halema‘uma‘u crater during Kīlauea's ongoing summit eruption. In the late afternoon on Sunday, October 3, the maximum fountain height was measured at approximately 11 meters (36 ft). This photo was taken from the south rim of Halema‘uma‘u looking to the west around 4:00 p.m. HST.

On Sunday, October 3, 2021, the late afternoon sunlight illuminated a perched edge of the active lava lake within Halema‘uma‘u, at Kīlauea summit. This view, looking to the northeast from the south rim of Halema‘uma‘u, shows the active lake surface (left) that is elevated a few meters (yards) above the lower trough along the crater wall (right).

KWcam image taken on October 2, 2021, at 6 a.m. HST. This image shows the ongoing eruption within Halemaʻumaʻu crater at the summit of Kīlauea. The eruption began the afternoon of September 29, 2021, as fissures in the floor of the crater; this activity is generating a lava lake that is slowly filling the crater. USGS webcam image. 

With permission from Hawa‘i Volcanoes National Park, Hawaiian Volcano Observatory (HVO) scientists continue to monitor the ongoing eruption within Halema‘uma‘u, at Kīlauea's summit. No significant changes have occurred over the past 24 hours.

The eruption in Halema‘uma‘u, at Kīlauea's summit, continues as of the evening of October 2, 2021. From the south rim of Halema‘uma‘u, this image shows at least three fountaining sources in the crater.

Lava continues to erupt from multiple vents on the base and west wall of Halemaʻumaʻu during the evening of October 2, 2021. Kīlauea summit sulfur dioxide (SO2) emission rates remain high and were estimated at around 20,000 tonnes per day the morning of September 30, 2021.

A telephoto image of the west vent in Halema‘uma‘u at the summit of Kīlauea, taken from the south rim of the crater. The west vent continues to be the most vigorous source, with sustained lava fountain heights of 10–15 meters (33–49 ft). Spatter from the lava fountain continues to build a horseshoe-shaped cone around it.

A telephoto image of the west vent in Halema‘uma‘u at the summit of Kīlauea, taken from the western rim of the crater. This fountain continues to produce the largest volcanic gas plume. Hawaiian Volcano Observatory scientists continue to monitor the eruption from an area within Hawai‘i Volcanoes National Park that remains closed to the public due to safety reasons.

A telephoto image of the south-central lava fountain in the Halema‘uma‘u lava lake at the summit of Kīlauea, taken from the south rim of the crater. This fissure continues to produce sustained lava fountain heights of 5–10 meters (16–33 ft), with occasional higher bursts of spatter. UGSG photo taken by L. DeSmither on October 2, 2021.

A telephoto image of the south-central lava fountain in the Halema‘uma‘u lava lake at the summit of Kīlauea, taken from the western rim of the crater. This is the most vigorous fountaining source within the south and central lava lake region and is 35 meters (115 ft) long with sustained fountain heights of 5–10 meters (16–33 ft). UGSG photo taken by L.

A telephoto image looking north at the largest island within the Halema‘uma‘u lava lake at Kīlauea summit. A low fountaining site along the southeast side of the main island (right), has built a small cone approximately 5 meters (16 ft) tall on the edge of the island. Occasional spatter was ejected from the vent at the top of the cone. UGSG photo taken by L.

A view of the new eruption within Halema'uma'u at Kīlauea summit at approximately 9 a.m. HST on the morning of October 1, 2021.

A helicopter overflight the morning of October 1, 2021, provided aerial views of the eruption within Halema‘uma‘u, at Kīlauea's summit. This view, looking to the west, shows an active lava fountain located within the south-central part of the lava lake. This fountain is only a few meters (yards) high. USGS photo by D. Downs.

Aerial image looking to the west of the large island that is floating within the middle of the lava lake in Halema‘uma‘u, at Kīlauea's summit. There are several vents with fountains reaching to just a few meters (yards) high. One of the vents along the eastern margin of the island has started to form spatter ramparts to enclose it. USGS photo by D. Downs.

Aerial view of the active lava lake and vents within Halema‘uma‘u crater, at the summit of Kīlauea. This view is looking to the northwest.

Aerial photo taken during a morning overflight on October 1, 2021, and looking at the west end of the lava lake within Halema‘uma‘u crater, at the summit of Kīlauea. The west vent that is feeding this part of the lava lake is visible; the base of this vent was well above the lava lake when it opened on the afternoon of September 29, 2021.

Aerial image looking to the southwest and showing fissures within Halema‘uma‘u, at Kīlauea's summit, producing lava fountains within the southern and south-central part of the lava lake. These lava fountains are less energetic than when the eruption started on September 29, 2021, but are still spattering to heights of about 5 meters (16 ft) or less.
