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 recent deflation pattern at the volcano over the last 48 hours reverted into an inflation in the midnight of 20 June.
This was followed by the ground uplift by approx. 1.5 microradians associated with the lava lake level by 3 meters indicating a rising batch of magma towards the surface.
The lava continues to keep the ooze out from the western fissure vent active along the southern and northern rim of the crater floor within the Halemaʻumaʻu lava lake.

Kilauea volcano update: deflation continues

Deformation data at Kilauea depicts continuing deflation (image: USGS)
Summit instruments detected a deflation starting around the midnight of 18 June with ground subsidence by approx. 2.5 microradians. The lava lake level has dropped by about 3 meters (10 ft) since the ground deformation started. This is most likely reflects reverts of magma batch movements under the surface leading to the lava lake sinking. ... Read all

Kilauea volcano (Hawaiian Islands, USA) - Smithsonian / USGS Weekly Volcanic Activity Report for 8 June-14 June 2022 (Continuing Activity)

HVO reported that lava continued to effuse from a vent in the lower W wall of Kilauea's Halema`uma`u Crater during 8-14 June, entering the lava lake and flowing onto the crater floor. The surface of the lava lake was continuously active all week, and the lake level was relatively stable. Nearly-continuous breakouts of lava occurred along the margins of the lake. ... Read all
