The effusive eruption within the Halemaʻumaʻu lava lake ended.
The lava flow stopped to be active from the western fissure vent and gradually continues to form slabs of dark, solidified crust of the lava lake surface.
The period of passive overturns and the exposing of the new lava at the surface occurred between 14-15 December. A smaller overturn event occurred on December 17 and another small event started around midnight and continues this morning on Dec 20.
The volcanic tremor has not shown significant variations.
Short-term electronic tilt has continued to detect deflation-inflation events over the past week and has been stable.
Sulfur dioxide (SO2) emissions reached to a 200 tonnes on 14 December.

The total cumulative rise of the crater floor has been about 143 meters (469 feet) and 111 million cubic meters (29.2 billion gallons) of lava had been erupted since the beginning of the latest eruption on September 29, 2021.

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.
