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 slightly in response to summit DI events but was generally 35 to 40 m (115 to 130 ft) below the floor of Halema`uma`u. There was a small collapse of the northwestern wall and rim of the Overlook crater on Tuesday, January 22.
On Kilauea’s east rift zone, surface lava flows remain active near the base of the pali and near the coast and are feeding weak ocean entries scattered along the sea cliff on both sides of the Hawai`i Volcanoes National Park boundary. Within Pu`u `O`o, small flows continue to occasionally erupt from openings on the floor of the crater. This includes the small lava lake on the northeast side of the crater floor—flows from there spilled onto the northeastern flank of the Pu`u `O`o cone for a few days early in the week..
There were no felt earthquakes in the past week on the Island of Hawai`i.
