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. The west edge of the delta collapsed into the ocean early on the morning of Nov. 2.
A breakout that began two weeks ago on the lower pali has remained active, sending flows west of the tube onto the coastal plain.
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.
Two earthquakes beneath Hawaii Island were felt during the past week.
A magnitude-2.5 earthquake occurred at 1:47 p.m. Thursday, Nov. 4 and was located 7 km (4 miles) southeast of Hawi at a depth of 30 km (19 miles).
A magnitude-2.2 earthquake occurred at 8:18 p.m. Tuesday, Nov. 9, and was located 6 km (4 miles) east of Honaunau at a depth of 14 km (9 miles).
