Lava flowing into Halema‘uma‘u from multiple channels 12/28/2020

Lava flowing from the western fissure vent feeds multiple channels. This video was taken by Hawaiian Volcano Observatory's geology field team on December 28, 2020, from 2:30 to 5:30 p.m. The team is located at an observation point on the rim of Halema‘uma‘u crater, and is using a telephoto lens to document fissure behavior. During the three-hour period, the field team

Kīlauea summit eruption - Dec. 28, 2020 at 5 a.m. HST

HVO field crews observed the continuing eruption in Halema‘uma‘u at Kīlauea's summit early this morning. Overnight, the western vent in the wall of Halema‘uma‘u continued to erupt, and the northern/eastern vent remained inactive. At approximately 4:30 a.m. HST today (Dec. 28), HVO field crews measured the lava lake as 179 m (586 ft) deep. Note that initial values reported

Using a laser ranger finder to measure Kīlauea summit eruption

HVO field crews have been using a laser range finder to measure the vertical distance between points of known elevation and features of the ongoing eruption, such as the lava lake surface level and the erupting vents. This morning, the eruption continues at the west vent in Halema‘uma‘u, and streams of lava about 40 m (131 ft) pour from the vent to the lava lake surface.

Evening views of the eruption in Halema‘uma‘u, 12/27/2020

27 December 2020 - Kīlauea Volcano US Geological Survey Hawaiian Volcano Observatory - Evening views of the eruption in Halema‘uma‘u. The west vent remained active overnight, with strombolian-like bursts and lava cascades. Lava cascading from the vent plunges into the lava lake in multiple places, causing local upwelling. As the cascades enter the lava lake, they cause the

Kīlauea summit eruption - Dec. 27, 2020 at 7:15 a.m. HST

The western vent in Halema‘uma‘u crater wall at Kīlauea summit remains active but field crews monitoring the eruption this morning (December 27) noted that its vigor is somewhat reduced from yesterday. Where three open channels were observed yesterday, there are only two today. Of the three locations that have been erupting at the west fissure vent, the eastern one has

Kīlauea summit eruption - Dec. 27, 2020 at 7:15 a.m. HST

HVO field crews were unable to observe early morning eruption activity in Halema‘uma‘u crater at Kīlauea's summit due to high winds. Upon return to the eruption site this morning, HVO field crews noted the reduced vigor at the western vent. The northern/eastern vent remains inactive. At approximately 7:30 a.m. HST today (Dec. 27), HVO field crews measured the lava lake as

December 27, 2020—Kīlauea summit eruption contour map

This map of Halema‘uma‘u at Kīlauea's summit shows 20 m (66 ft) contour lines (black) that mark locations of equal elevation above sea level (asl). The map shows that the lava lake (approximate outline marked in red) has filled 177 m (580 ft) of Halema‘uma‘u since the eruption began at approximately 9:30 p.m. HST on December 20, 2020 (nearly one week ago). The lava lake

Kīlauea summit eruption - Dec. 26, 2020 at 5:15 a.m. HST

The eruption continues in Halema‘uma‘u crater at Kīlauea's summit. HVO field crews observing the activity overnight noted that at approximately 2:40 a.m. HST December 26, 2020, activity at west vent in the wall of Halema‘uma‘u rejuvenated: the west vent has became more active than the northern vent. Since the start of the eruption on December 20 at 9:30 p.m. HST, the

Kīlauea summit west vent - Dec. 26, 2020 at 5:15 a.m. HST

As of about 2:40 a.m. HST on December 26, 2020, activity at the west vent in Halema‘uma‘u crater wall at Kīlauea's summit has increased. This photo, taken at approximately 5:15 a.m. HST shows fountaining at the west vent, and lava pouring from the north end of the fissure into the growing lava lake. HVO field crews monitoring the activity overnight measured the west vent

Overflight of Kīlauea's summit Lava Lake and Fissure

A helicopter overflight on December 26, 2020, provided aerial views of the eruption in Halema‘uma‘u. This video, which is sped up 3 times, shows the lava lake and active west vent that rejuvenated just before 3 a.m. HST today. Visual and thermal imagery collected during the overflight are used to map the ongoing activity.

December 26, 2020—Kīlauea summit eruption thermal map

A helicopter overflight yesterday (Dec. 26, 2020) at approximately 9:30 AM HST allowed for aerial visual and thermal imagery to be collected of the new eruption within Halema'uma'u crater at the summit of Kīlauea Volcano. This preliminary thermal map shows that the new lava lake is 790 m (864 yd) E-W axis and 520 m (569 yd) in N-S axis. The most recent estimate of lake
