Kīlauea summit eruption in Halemaʻumaʻu crater - October 2, 2021

Eruptive activity continues in Halema‘uma‘u crater, at the summit of Kīlauea. The west vent remains active with low fountaining in a slightly perched pond set within the cone. Lava pours through a short spillway into the lava lake.

Morning views of Halema‘uma‘u west vent & lava lake - October 23, 2021

Morning views of the eruption within Halema‘uma‘u crater, at Kīlauea summit, on October 23, 2021. Variable west vent fountain heights are visible in this video, which is shown at 5 times speed. Sporadic foundering, when cooler lava crust on the surface sinks back into the liquid portion of the lava lake below, is also visible across the active west portion of the lava lake

Morning views of the eruption in Halema‘uma‘u - October 23, 2021

Morning views of the eruption within Halema‘uma‘u crater, at Kīlauea summit, on October 23, 2021. This view is from the south rim of the crater. Lava continues to erupt from a single vent on the western wall of the crater. Lava fountains within the cone and spills out of the cone opening, flowing east into the lake.

Kīlauea summit overflight - October 15, 2021

A morning overflight of Kīlauea summit on October 15, 2021, provided aerial views of the eruption within Halema‘uma‘u. Lava erupts from a single vent on the western wall of the crater. The vent has a spatter cone around it, with an opening to the east from which lava flows into the lava lake.

Lava fountaining in Halema'uma'u crater—October 12, 2021

Lava continues to erupt from the western vent in Halema‘uma‘u. On October 12, a short-lived vent (erupting for approximately 10 hours) was present to the north of the main vent (right). Lava fountaining from the main vent was 10–15 meters (30–50 ft) above the lake surface, with larger bursts exceeding the height of the cone (30 meters or 100 ft). Fountaining at the smaller

Kīlauea summit eruption—October 12, 2021

The eruption continues within Halema‘uma‘u crater, at the summit of Kīlauea. The western vent supplies lava into the lava lake through a short spillway. Consistent fountain heights of 10–15 meters (30–50 ft) were interrupted by frequent larger busts of spatter exceeding the height of the cone (30 m or 100 ft).

Eruptive activity in Halema‘uma‘u crater—October 12, 2021

Eruptive activity continues at the west vent in Halema‘uma‘u crater, at the summit of Kīlauea. When this video was taken on October 12, a small subordinate vent was present on the north side of the main fountaining vent. The main fountaining source was supplying lava into the lake via a short spillway.

October 10, 2021—Kīlauea, fountaining at west vent of Halema'uma'u

Kīlauea summit eruption lava fountain height in Halema‘uma‘u crater on October 10, 2021 was highly variable. A persistent low fountain a few meters (yards) tall was frequently interrupted by larger series of bursts throwing lava more than 15 meters (50 feet) into the air and onto the interior walls of the vent cone.

October 7, 2021 — Kīlauea volcanic vent

The eruption continues in Halema‘uma‘u crater, at the summit of Kīlauea. Lava fountaining no longer emerges from the central portion of the lake, with fountaining limited to the west vent shown here. Low fountaining within the cone supplies lava into the lake via a short spillway.

Kīlauea summit eruption field work – October 7, 2021

An HVO geologist makes observations, collects data, and maintains instruments during the ongoing eruption within Halema'uma'u. This video shows some of the typical field work HVO geologists do during eruption monitoring, including collecting high-resolution videos, photos, and thermal images, taking laser rangefinder measurements, and maintaining field camera stations.

Lava fountains - western fissure, Halema‘uma‘u, Kīlauea - Oct 5, 2021

Lava fountains from the western fissure vent in the Halema‘uma‘u crater wall, at Kīlauea's summit during the ongoing eruption. The shaking at the end of the video is due to strong wind gusts moving the tripod. This video clip was recorded on October 5, 2021, from the southern crater rim.
