This February 10th, 2021 Kilauea Volcano Eruptions update presentation video contains one new time lapse video made from USGS thermal images during the ongoing 2020 eruptions. In addition there is also further processed USGS overflight video and images with additional improvements such as motion enlargements, sharpness increase, vibration reduction and additional audio & visual layers to enhance the viewing experience. The media obtained from USGS and Google Earth with some of the details from; USGS at https://www.usgs.gov/volcanoes/kilauea/photo-video-chronology and earthquakes data. According to the USGS HVO Scientists, the Halemaumau lava lake is still getting bigger and now around 214 m (702 ft) deep. The lava lake was 191 m (623 ft) deep Monday afternoon (Jan. 4)
Activity Summary: Kīlauea Volcano is erupting. Lava activity is confined to Halemaʻumaʻu with lava erupting from a vent on the northwest side of the crater. As of the morning of February 7, the lava in the western, active portion of the lake in Halemaʻumaʻu was about 214 m (702 ft) deep, with the eastern portion of the lava lake solidified at the surface. SO2 emission rates remain elevated.
Summit Observations: The most recent sulfur dioxide emission rate measurements from February 1 are about 2,200 t/d—lower than the emission rates from the pre-2018 lava lake (3,000–6,500 t/d). The summit tiltmeters show the onset of inflationary tilt yesterday at about 6pm, with inflationary tilt continuing this morning. Seismicity remains elevated but stable, with elevated tremor and a few minor earthquakes.
East Rift Zone Observations: Geodetic monitors indicate that the upper portion of the East Rift Zone (between the summit and Puʻu ʻŌʻō) contracted while the summit deflated at the onset of this eruption. There is no seismic or deformation data to indicate that additional magma is currently moving into either of Kīlauea’s rift zones. SO2 and H2S emissions from Puʻu ʻŌʻō were below instrumental detection levels when measured on January 7.
Halemaʻumaʻu lava lake Observations: Lava from the west vent continues to supply Halema‘uma‘u crater with lava. The overall vigor of lava lake activity increased slightly overnight, likely related to the onset of summit inflation.
HVO scientists collect detailed data to assess hazards and understand how the eruption is evolving at Kīlauea’s summit, all of which are shared with the National Park Service and emergency managers. Access to this area is by permission from, and in coordination with, Hawai‘i Volcanoes National Park. HVO scientists monitor the eruption from within an area of Hawai‘i Volcanoes National Park that remains closed to the public for safety reasons. Associated USGS thermal imaging, illustration maps, time lapse and overflight video with more pronounced helicopter and wind sounds are also provided.
It is very exciting to see that Hawaii Kilauea Volcano Halemaumau lava lake is back and looks like much much bigger than before. Hopefully Visitors of the Volcano National Park will be able to enjoy these amazing views with their own eyes.
January 2021 is Hawaiʻi Island’s 12th annual Volcano Awareness Month.
According to the USGS Hawaii Volcano Observatory HVO website;
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. Currently rise of the lava lake slowed down
Here is my Lava Flow Rate calculation;
In reference to Beginning 2020-12-20 21:30 HST and the Summit Eruption Reference Map 2020-12-27 16:00 HST stats with 5.6 Billion Gallons, and with Time Difference of 6 days, 18 hours, 30 minutes or 162.5 hours or 9750 minutes or 585000 seconds; Therefore 5.6 billion gallons of lava / 585000 seconds = 9572.6 gallons of lava per second (36236.2 liters / second) average flow for approximately the first week. Lava specific weight is about 3100 kg/m3 therefore flow rate is ~112 metric tons per second.
