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 to be active. Over the past week, the flow front has not advanced significantly and has lingered near the boundary of Hawai`i Volcanoes National Park about 950 m (0.6 miles) from the coastline; there was no active ocean entry. Within Pu`u `O`o, a lava pond was active in the eastern portion of the crater.

No earthquakes were reported felt across the island of Hawai`i during the past week.

Time-lapse movie of the Peace Day Flow along Kilauea’s coastal plain.

Lava flows remain active on the pali and coastal plain, but the flow front has made no significant progress towards the ocean over the past week. This image is a composite of a thermal image and a normal photograph, with active breakouts shown by yellow and white areas, and recent, but inactive, flows shown in red and purple. The active flow front, in the lower left portion of the image, was about 1 km (0.6 miles) from the ocean Friday (June 29).

Map showing the extent of lava flows erupted during Kilauea’s ongoing east rift zone eruption and labeled with the years in which they were active. Episodes 1-48b (1983-1986) are shown in gray; episodes 48c-49 (1986-1992) are pale yellow; episodes 50-53 and 55 (1992-2007) are tan; episode 54 (1997) is yellow; episode 58 (2007-2011) is pale orange; the episode 59 Kamoamoa eruption (March 2011) is at left in light reddish orange; and the episode 60 Pu‘u ‘O‘o overflows and flank breakout (Mar-August 2011) are orange. The currently active Peace Day flow (episode 61) is shown as the two shades of red—light red is the extent of the flow from September 21, 2011, to June 15, 2012, and bright red marks flow expansion from June 15 to June 29. The active lava tube is delineated by the yellow line within the active flow field. The contour interval on Pu‘u ‘O‘o is 5 m.
