A lava lake within the Halema`uma`u Overlook vent produced nighttime glow that was visible from the Jaggar Museum overlook and via HVO’s Webcam during the past week. The lake level fluctuated in response to a summit deflation–inflation cycle, ranging between about 25 and 60 m (80–200 ft) below the floor of Halema`uma`u.
On Kilauea’s east rift zone, breakouts from the Peace Day tube remain active above and at the base of the pali and on the coastal plain, and small ocean entries are active on both sides of the Hawai`i Volcanoes National Park boundary. In addition, the Kahauale`a flow, fed directly from a spatter cone on the northeastern edge of Pu`u `O`o’s crater floor, continues to advance slowly toward the northeast across a plain of 1980’s-era `a`a flows.
There were no felt earthquakes in the past week on the Island of Hawai`i.
