[B1cam] - Halemaʻumaʻu and lava lake from the down-dropped block

Live view of Halemaʻumaʻu - temporary webcam image showing the crater lava lake from the east rim and down-dropped block [B1cam].

Disclaimer: The webcams are operational 24/7 and faithfully record the dark of night if there are no sources of incandescence or other lights. Thermal webcams record heat rather than light and get better views through volcanic gas. At

The lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, remains active
May 14, 2021

View of the active lava lake area in Halema‘uma‘u—Kīlauea, May 14

The lava lake in Halema‘uma‘u crater, at the summit of Kīlauea, remains active, although surface incandescence (glowing red lava) has become less frequent over the last few days. In this view looking northwest, two elongated lobes oriented west (left) to east (right) with a relatively smooth shiny grey surface are visible in the center of the photo. These two lobes

Kīlauea summit overflight - May 13

USGS Hawaiian Volcano Observatory geologists conducted an overflight of Kīlauea's summit on the morning of May 13. Though no incandescence was visible during the overflight, field crews monitoring the ongoing eruption in Halema‘uma‘u from the ground observed a small amount of fluid lava on the surface later in the day. In this aerial photo, the west vent area is in the

More of Kīlauea's lava lake surface in Halema‘uma‘u crater has solidified in recent weeks, evident in this May 13 aerial view

Kīlauea summit overflight - May 13

More of Kīlauea's lava lake surface in Halema‘uma‘u crater has solidified in recent weeks, as is evident in this aerial view taken yesterday, May 13. However, gas emissions and small patches of active lava on the surface indicate that the eruption continues. Most recently, gas emissions were measured as 225 tonnes per day on May 12. The bluish-tinged plume of volcanic gas

Kīlauea summit overflight - May 13

A low, oblique aerial view of the west vent in Halema‘uma‘u at Kīlauea's summit (upper right) taken during an overflight on May 13. The area of active lava has slowly been decreasing in recent weeks, but not all of the lava lake surface has stagnated. Portions of the lake surface continue to resurface via a process called foundering. During foundering, the dense solidified

Kīlauea summit overflight - May 13

Near Kīlauea Visitor Center, the Ha‘akulamanu trail within Hawai‘i Volcanoes National Park passes through the Sulphur Banks area. Fumaroles in this area emit different sulfur gases, including sulfur dioxide (SO2) and hydrogen sulfide (H2S), and are sampled approximately every three months by USGS Hawaiian Volcano Observatory gas geochemists to track

USGS Hawaiian Volcano Observatory geologists observed fluid lava on the surface of the lava lake in Halema‘uma‘u, at the summit

Halema‘uma‘u lava lake, Kīlauea summit eruption—May 13, 2021

USGS Hawaiian Volcano Observatory geologists observed fluid lava on the surface of the lava lake in Halema‘uma‘u, at the summit of Kīlauea, while monitoring the eruption on May 13. Two areas of ponded lava exhibited foundering, during which more-dense solidified crust sinks into the lava lake and is replaced by less-dense liquid lava from below. This photo shows the

The area of solidified crust at the surface of Halema‘uma‘u's lava lake, has been growing over the past several weeks

Halema‘uma‘u lava lake, Kīlauea summit eruption—May 13, 2021

The area of solidified crust at the surface of Halema‘uma‘u's lava lake, at the summit of Kīlauea, has been growing over the past several weeks. This may make it seem that the eruption is over but lava continues to be supplied to the lava lake from below. With National Park Service permission, USGS Hawaiian Volcano Observatory geologists observe this eruption from within

Halema‘uma‘u lava lake, Kīlauea summit eruption—May 13, 2021

The eruption in Halema‘uma‘u, at the summit of Kīlauea, continues. Gas emissions, last measured on May 12, were 225 tonnes per day. This photo, taken on May 13, shows the bluish-tinged plume of volcanic gas being emitted from the western vent complex within Halema‘uma‘u crater. USGS image by K. Mulliken.

Digital elevation model of crater and lava lake

Halema‘uma‘u DEM May 13, 2021

A helicopter overflight on May 13, 2021, at approximately 11:30 a.m. HST allowed for aerial visual and thermal imagery to be collected of the eruption within Halema‘uma‘u crater at the summit of Kīlauea Volcano. The visual images were used to create a digital elevation model (DEM) of the crater, shown here. The many islands and levees formed at different times during the

A wide view of Halema‘uma‘u from the western crater rim, at the summit of Kīlauea

Halema‘uma‘u eruption activity on May 12, 2021 — Kīlauea summit

A wide view of Halema‘uma‘u from the western crater rim, at the summit of Kīlauea. The west vent (lower left) continues to supply lava into the lake through a submerged inlet. Much of the western active lava lake surface has crusted over in the last few weeks as the effusion rate remains low. USGS photograph taken by D. Downs on May 12, 2021.

Halema‘uma‘u eruption activity on May 12, 2021 — Kīlauea summit

A close up view of the western portion of the lava lake within Halema‘uma‘u, at Kīlauea summit. A weak gas plume is emitted from the western fissure vent (left), with the most recent sulfur dioxide emission rate measured at 150 tonnes per day on May 11. USGS photograph taken by D. Downs on May 12, 2021 from the west rim of Halema‘uma‘u.
