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.

Kilauea volcano (Hawaiian Islands, USA) - Smithsonian / USGS Weekly Volcanic Activity Report for 28 September-4 October 2022 (Continuing Activity)

Wed, 5 Oct 2022, 14:00 14:00 PM | BY: VN
HVO reported that lava continued to effuse from a vent in the lower W wall of Kilauea's Halema`uma`u Crater during 27 September-4 October, entering the lava lake. The active part of the lake stayed at a relatively steady level through the week, varying only slightly. Sulfur dioxide emissions were approximately 970 and 1,800 tonnes per day on 28 and 30 September, respectively.
The Volcano Alert Level remained at Watch (the second highest level on a four-level scale) and the Aviation Color Code remained at Orange (the second highest level on a four-color scale).

HVO reported that lava continued to effuse from a vent in the lower W wall of Kilauea's Halema`uma`u Crater during 20-27 September, entering the lava lake and flowing onto the crater floor. The continuously active part of the lake dropped 10 m, regained 3 m during 19-22 September, and then was unchanged the rest of the week. Breakouts of lava occurred at the W and N margins of the lake during most of the week. ... Read all
