A lava lake within the Halema`uma`u Overlook vent resulted in night-time glow that was visible from the Jaggar Museum overlook during the past week. The lake has been about 60–80 m (200–260 ft) below the floor of Halema`uma`u Crater and visible by HVO’s Webcam through much of the last month. This past week the level fluctuated slightly due to several deflation-inflation (DI) cycles at the summit.
On Kilauea’s east rift zone, surface lava flows on the pali and coastal plain continued advancing towards the ocean. As of Wednesday, June 20, the flows were about 800 m (0.5 miles) from the ocean; there was no active ocean entry. Within Pu`u `O`o crater, a lava pond was active and several small lava flows were erupted onto the crater floor over the past week.
Three earthquakes were reported felt across the island of Hawai`i during the past week. A magnitude-3.0 earthquake occurred at 2:31 p.m., HST, on June 14, 2012, and was located 13 km (8 mi) southeast of Waimea at a depth of 15 km (9 mi). A magnitude-3.8 earthquake occurred at 2:18 p.m., on June 15 and was located 14 mi (23 km) southwest of Waikoloa Village at a depth of 40 km (25 mi). A magnitude-2.9 earthquake occurred at 1:01 p.m., HST, on June 19 and was located 4 km (2 mi) southeast of Kilauea summit at a depth of 4 km (2 mi).

Time-lapse movie of the ‘Peace Day Flow’ on the coastal plain
Having recently visited the peace day flow on the flats, I can tell you the night web cam views are over exposed. The flow is nearly stagnant other then the far western section. Lots of still warm lava so, watch where you set your pack.
