A lava lake within Halema‘uma‘u produced nighttime glow that was visible via HVO’s Webcam during the past week. The lava lake level peaked with summit inflation early last week, and then dropped again with deflation. On June 5, the lava level was 48 m (157 ft) below the rim of the Overlook crater.

On Kīlauea’s East Rift Zone, the Kahauale‘a 2 flow remains active but has diminished in vigor. The flow front stalled at 8.8 km (5.5 miles) northeast of its vent on Pu‘u ‘Ō‘ō in mid-May. The most distant active flows are now just over 6 km (4 miles) from Pu‘u ‘Ō‘ō and are relatively weak. Several small spatter cones within Pu‘u ‘Ō‘ō crater continue to produce glow.

There were no earthquakes reported felt in the past week within the State of Hawaii.
