Lava continues to enter the lava tube system and is carried downslope to Puhi-o-Kalaikini lava delta, near Kalapana, where it enters the ocean and creates a large steam plume. Lava breakouts from the tube fed small surface flows that were active near the end of Highway 130, just west of Kalapana, through much of the week. Lava flows were active sporadically within the Puu Oo crater through the week as well.
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.
