Kilauea Summary

 

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 update: activity slowed down rapidly, vents within eastern and central lakes ceased


The effusive eruption within the Halemaʻumaʻu crater floor continues to be significantly decreased over the past 24 hours.
Both vents, previously feeding the eastern lava lake and central lava pond, seem to have stopped being active.
The 2021-2022 western lava lake remains active, but poorly supplied by lava flows circulating within the lake, which in turn develop into a gradually forming solidified crust. The reason for this activity is a recent rapid subsidence of ground (so-called deflation) in the early morning of 17 February.
A renewed effusive activity is expected to resume and it is supposed to follow the usual pattern of reverting to inflation and rising lava lake levels in the near future.
Sulfur dioxide (SO2) emissions reached to a 2,000 tonnes on 13 February.
Furthermore, heavy rains continue to affect the volcano area by creating an abundant steam over the Halemaʻumaʻu and considerably limiting a visibility into the crater.
