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.

This animated GIF is captured from a USGS video which shows both lava erupting from a fissure and a wind vortex (lavanado) over the lava lake at Kīlauea Volcano.

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.

A helicopter overflight yesterday (Dec. 28, 2020) at approximately 10:30 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 lake area has not changed significantly since the thermal map that was made on December 26.

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.

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.

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 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.

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.

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 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.

On the evening of December 25, 2020, the eruption in Halema‘uma‘u crater at Kīlauea's summit continued. Throughout the day, fountaining at two vents continued to feed the rising lava lake which slowly fills Halema‘uma‘u. This photo, taken at approximately 6 p.m.

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.
