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. After recovering slightly from a deflation-inflation (DI) event at Kilauea’s summit two weeks ago, the lava lake level dropped again this week during the deflation phase of another DI event. This deflation had not yet transitioned to inflation as of this writing (Thursday, December 27).

On Kilauea’s east rift zone, surface lava flows remain active on the coastal plain, but were not entering the ocean as of December 27. The active flows straddle the eastern boundary of Hawai`i Volcanoes National Park. Within Pu`u `O`o, glow and small, sporadic lava flows emanate from openings in the northeastern, northwestern, and southeastern parts of the crater floor.

No earthquakes were reported felt in the past week on the Island of Hawai`i.
