The June 27th lava flow from Puʻu ʻŌʻō remained active on Kīlauea Volcano’s East Rift Zone. The active flow front was 14.6 km (9.1 mi) from the vent and 0.5 km (0.3 mi) from the east boundary of the Wao Kele o Puna Forest Reserve as of September 11 (the time of this writing), and moving in a northeasterly direction. Within the Puʻu ʻŌʻō crater, glow was visible above several small lava ponds and outgassing openings in the crater floor.

The summit lava lake within HalemaÊ»umaÊ»u Crater produced nighttime glow that was visible via HVO’s webcam over the past week. The lava lake level ranged from 55 to 65 m (180‒215 ft) below the rim of the Overlook crater.

There were no earthquakes in the past week reported felt on the Island of Hawai‘i.
