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

A lava lake within the Halema‘uma‘u Overlook vent produced nighttime glow that was visible via HVO’s Webcam during the past week. A deflation-inflation cycle (DI event) occurred early in the week, and the lava-lake level fluctuated correspondingly.

On Kīlauea’s East Rift Zone, the Kahauale‘a 2 flow continues to advance slowly into the forest northeast of Pu‘u ‘Ō‘ō. The active front of the flow is about 6 km (4 miles) northeast of Pu‘u ‘Ō‘ō.

There were no earthquakes in the past week that were reported felt on the Island of Hawai‘i.
