Volcano Watch: Kilaueau update for week of Nov. 11

(Activity updates are written by scientists at the U.S. Geological Survey’s Hawaiian Volcano Observatory.)

Lava continues to enter the lava tube system and is carried downslope to the Puhi-o-Kalaikini lava delta, near Kalapana, where it enters the ocean and creates a steam plume. Several small breakouts have been active this week on the lower pali and coastal plain, with most of the lava directed west of the lava tube.

At Kilauea’s summit, the circulating lava lake deep in the collapse pit within the floor of Halemaumau Crater has been visible via Webcam throughout the past week. The circulation pattern was interrupted sporadically by abrupt increases in the height of the lava surface.

These periods of high lava level have been short-lived, lasting up to several hours, and each ended with a sudden drop of the lava surface back to its previous level. Volcanic gas emissions remain elevated, resulting in high concentrations of sulfur dioxide downwind.

No earthquakes beneath Hawaii Island were reported felt during the past week.
