This December 29, 2020 Kilauea Volcano Eruptions update presentation video contains media obtained from USGS and Google with some of the details from; USGS at https://www.usgs.gov//kilauea/photo-video-chronology and data. According to the USGS HVO Scientists “…The lava lake appears to be slowly draining at the northern fissure site”. Associated USGS thermal imaging, illustration maps, fixed vent lava discharge at night video are also provided. The Vent 2020-12-27 vent activity video at night was received with partial damage to the file. So only the good parts made to this presentation…

It is very exciting to see that Hawaii Kilauea Volcano Halemaumau lava lake is back and looks like much bigger than before. Hopefully Visitors of the Volcano National Park will be able to enjoy these amazing views with their own eyes.

According to the USGS Hawaii Volcano Observatory HVO website;

“Photo and Video Chronology – Kīlauea – December 20, 2020
Release Date: DECEMBER 20, 2020
Shortly after approximately 9:30 p.m. HST, ( 2:30 a.m. EST Monday December 21st ) the USGS Hawaiian Volcano Observatory (HVO) detected glow within Halemaʻumaʻu crater at the summit of Kīlauea Volcano. An eruption has commenced within Kīlauea’s summit caldera. The situation is rapidly evolving and HVO will issue another statement when more is available. ”

“Recent Observations:
An earthquake swarm beneath Kīlauea summit began around 8:30 p.m. HST on the of December 20, ( 1:30 a.m. EST Monday December 21st ) accompanied by ground deformation detected by tiltmeters. A bright glow and vigorous steam plume, generated by the boiling water lake in Halemaʻumaʻu, was subsequently observed on HVO webcams beginning approximately 9:30 p.m. HST. HVO scientists responded immediately and visually confirmed from the field that lava was visible within Halemaʻumaʻu. The steam plume dissipated shortly thereafter. Activity over the past ten hours has been characterized by three fissure vents on the north and northwest walls of Halemaʻumaʻu crater. Fountaining lava at these vents is estimated to be up to 25 m (82 ft) high; the vents are feeding lava flows into the base of Halemaʻumaʻu crater, which is being filled with a growing lava lake.

The lava lake has been rising approximately several meters (yards) an hour since the eruption began. The current lava lake exhibits a circulating perimeter, but stagnant center.

The event has been accompanied by only moderate amounts of deformation, indicating deflation of a magma reservoir under Halema’uma’u. Rates of tilting have decreased slightly since the beginning of the eruption.

Increased rates of seismicity in the summit region continue. Some of these may be felt. A magnitude-4.4 earthquake located beneath Kīlauea Volcano’s south flank occurred on Sunday, December 20, at 10:36 p.m. HST.

Visitors to the Hawai’i National Park should note that under southerly (non-trade) wind conditions, rockfalls and explosions result in a dusting of powdery to gritty ash composed of volcanic glass and rock fragments. These ashfalls represent a minor hazard, but visitors should be aware that dustings of ash at areas around the Kīlauea summit are possible.”

“As of about 4:45 a.m. HST on Dec. 22, HVO field crew noted that the lava lake rose 3 meters in 3.5 hours. The lake surface is now 487 m (1598 ft) below the crater rim observation site, indicating that the lake has filled 134 m (440 ft) of the bottom of Halema‘uma‘u crater. This is more than double the depth of the water lake that was in the crater until the of Dec. 20 when it was vaporized. Fountaining continues at two locations, more vigorously at eastern vent, and both vents continue to feed the growing lava lake.”
