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 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.

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.

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.

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.

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 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.

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.

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.

Lava lake level measurements collected during a field visit of Kīlauea Volcano's summit around 2:15 p.m. HST on December 25, 2020, were used to create a preliminary lava lake depth map. When compared to pre-eruption topographic models, it shows that the bottom of Halema'uma'u crater has been filled by almost 176 m (578 ft) of lava. Map by H.

HVO field crews measured Kīlauea's summit lava lake this morning (Dec. 25) around 7:30 a.m. HST. The lake surface is now 445 m (1460 ft) below the crater rim observation site, indicating that the lake has filled 176 m (577 ft) of the bottom of Halema‘uma‘u crater.

This thermal timelapse (from F1cam webcam) shows the switch from water lake to lava lake in Halema‘uma‘u, spanning December 20 to December 24. During the initial phase of lava appearing in the crater, a large steam plume is generated as lava interacts with and boils off the water lake.

Beginning on December 20, 2020, fissure vents opened in the Halema‘uma‘u crater. The former water lake quickly boiled away and, fed by two active fissures, the new lava lake is rising. How high is the lava in the approximately 54 acre lake?
