Floating islands within eastern lava lake being submerged
Update Sat 04 Feb 2023 17:51

The effusive activity within the Halemaʻumaʻu crater floor continues.
The eastern lava lake continues to be at stable values. Two smaller floating islands within it seem to disappeared as they being already submerged over the past day, the HVO reported. A new lava crust began to form itself against the north and east levees.
The small lava fountain, located in the southern part of the lake, continues to be active and is getting back to previous average levels with height of 1-2 meters.
The 2021-2022 western lava lake continues to be active and remains unchanged within the Halemaʻumaʻu crater.

The ground deformation parameters have been flat, meaning no inflation nor deflation.
Sulfur dioxide (SO2) emissions reached to a 3,000 tonnes on 20 January.

The effusive eruption within the Halemaʻumaʻu crater continues with little changes as it's being seen waned over the past two days.
The eastern lava lake started to crust itself during the morning of 1 February and formed a narrow bridge-like crust section through the center of the lake (so-called isthmus) separating it into the northern and southern parts. This phenomenon is well visible in the latest Sentinel-2 satellite image from 1 Feb portraying two smaller glowing yellow patches of lava.
The two active areas in the eastern lava lake were about 25 acres in size measured on 17 January where each one showed independent and opposite surface convection movements from levees towards the isthmus direction.
The lava spattering in the southern part of the eastern lava lake disappeared from view for 45 minutes at 11:15 PM local time on 1 February, but it returned back at midnight. At about 01:00 AM local time, the lava surface from the southern part invaded the whole eastern lava lake including levees boundaries and the isthmus and returned to the original single lava lake at about 04:00 AM yesterday morning. It currently continues at stable conditions again, suggesting that there is a delicate equilibrium between heat and magma supply and loss (through cooling and mild emissions during degassing).
The 2021-2022 western lava lake continues to be active and remains unchanged within the Halemaʻumaʻu crater.

The effusive eruption at the volcano continues.
Both lava lakes, the large one in the eastern half of the crater and 2021-2022 western, smaller one, continue to be active within the Halemaʻumaʻu crater.
The eastern lava lake is currently well-defined by its levee boundaries, though there are periods of frequent overflows.
The flux of SO2 emissions reached to a 3,000 tonnes on 20 January.

The effusive eruption within the Halemaʻumaʻu crater continues.
The main activity is confined to the 2023 large lava lake, located in the eastern half of the crater, as well as to the 2021-2022 smaller, western lava lake.
The fissure vent continues to erupt one prevailing lava fountain, about 6-7 meters tall, feeding lava into the eastern lava lake. The current lava lake area refers to approx. 30 acres measured on 10 January.
Summit tiltmeters monitored an inflation pattern early yesterday, consistent with the inflation phase of a summit deflation-inflation event.
The volcanic tremor has not shown significant variations.
Sulfur dioxide (SO2) emissions reached to a 3,500 tonnes on 9 January.

The effusive eruption from the eruptive vents in the eastern half of the Halemaʻumaʻu crater continues.
Judging from the here, several small lava fountains have reduced themselves into one dominant lava bursting.
The summit of the volcano has been inflated until about midday yesterday, but later on, it reverted to a deflation mode again.
SO2 emissions reached to a 3,500 tonnes on 9 January.

The effusive eruption within Halemaʻumaʻu crater has slightly slowed down over the past 24 hours.
Small, sustained lava fountains continue to feed the lava spreading into the newly formed lava lake, currently concentrated in the eastern half of the crater.
The flux of SO2 emissions reached to a 4,000 tonnes on 8 January.

The effusive activity is confined within the Halema'uma'u crater.
The vast area of the crater floor is being covered by lava flow field with slabs of dark, solidified crust that have continued to shift on the lava field surface, accompanied by typical bright orange lava glow where several weak lava spattering is seen between them.
The HVO observatory doesn't expect the eruption to migrate elsewhere out of the summit area.
The alert status is being lowered from "Warning" to "Watch" as the effusion rate has been declining over the past hours and the Aviation Color Code from "Red" to "Orange" because there is currently no threat of significant volcanic ash emission into the atmosphere outside of the hazardous closed area within Hawai'i Volcanoes National Park.

The new effusive eruption, beginning yesterday, continues.
Multiple lava fountains, about 10 meters tall, continue to be produced from the fissure vent located in the central-eastern part of Halema'uma'u crater floor. Some lava jets surpassed 30 meters high at 07:45 PM local time yesterday and several ones exceeded 50 meters during the onset of the eruption.
Lava flows have covered up about 300 acres of the crater floor with 10 meters depth so far.
An initial pre-eruption inflation pattern switched to a deflation phase around 05:00 PM local time yesterday reflecting continuing and smooth magma intrusion, supported also by a resuming seismic tremor.
Sulfur dioxide (SO2) emissions continue at elevated levels.

A new eruption started at Kilauea in the afternoon of 5 January.
At approx. 04:34 PM local time, the HVO surveillance cameras detected a glow within Halemaʻumaʻu crater. Later on, a new eruptive fissure started to appear and erupt small lava fountains generating lava flows where they have been slowly spreading into various directions and gradually covering the solidified crater floor. Typical slabs of dark, solidified crust have continued to shift on the lava field surface, accompanied by typical bright orange lava glow between them.
Therefore, a decision has been made to rise the Volcanic Alert Level to "Red".
