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 between about 25 and 30 m (80–100 ft) below the floor of Halema`uma`u.
On Kilauea’s east rift zone, surface lava flows remain active about mid-way across the coastal plain along with some weak activity near the coast. Small ocean entries remain active just inside and just outside Hawai`i Volcanoes National Park.
At Pu`u `O`o, lava erupting from a complex of spatter cones on the northeast side of the crater floor — the former site of a small lava lake — is feeding a slow-moving pahoehoe flow spreading toward the northeast. Other spatter cones on the crater floor have sporadically erupted tiny, short-lived flows, at least one of which traveled a few hundred meters (yards) down Pu`u `O`o’s southeast flank.
There were no felt earthquakes in the past week on the Island of Hawai`i.
