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.

HVO reported that lava continued to effuse from a vent in the lower W wall of Kilauea's Halema`uma`u Crater during 9-15 November, entering the lava lake and flowing onto the crater floor. On 9 November the sulfur dioxide emission rate was 600 tonnes per day (t/d). The active part of the lake remained at a steady level all week.
The Aviation Color Code and the Volcano Alert Level remained at Orange and Watch, respectively.
