A lava lake within the Halema‘uma‘u Overlook vent produced nighttime glow that was visible via HVO’s Webcam during the past week. Two deflation-inflation cycles (DI events) occurred during the week (as of Thursday, October 31), and the lava lake level fell, then correspondingly rose again during each cycle.

On Kīlauea’s East Rift Zone, a breakout from the Peace Day tube above the pali was probably still active on October 29, based on infrared satellite imagery. The Kahauale‘a 2 flow, fed from a spatter cone on the northeast edge of the Pu‘u ‘Ō‘ō crater, continues to advance slowly across old flows and into the forest. Its tip was 5.8 km (3.6 miles) northeast of Pu‘u ‘Ō‘ō when last mapped on October 21.

No earthquakes were reported felt on the Island of Hawai‘i during the past week.
