Breakouts remain active northeast of Pu‘u ‘Ō‘ō, but on today's overflight we observed a decrease in overall activity. In particular, breakouts that had been active closer to Pu‘u ‘Ō‘ō on previous days, around Pu‘u Kahauale‘a, were inactive today. The active breakouts began about 4 km (2.5 miles) northeast of Pu‘u ‘Ō‘ō and reached nearly 8 km (5 miles). This farthest distance has not changed significantly in recent weeks.

This photograph looks west along the East Rift Zone, towards Pu‘u ‘Ō‘ō and Kīlauea's summit. Pu‘u ‘Ō‘ō can be seen near the horizon, on the left side of the image. The farthest active lava today was near the smokey area in the left side of the image. Kīlauea's summit plume can be seen in the distance in the upper right portion of the photograph.

Breakouts have further buried Pu‘u Kahauale‘a in recent weeks. The cone was originally covered in thick vegetation, but today only a single dead tree stands on the remnants of the cone rim.

The summit lava lake today was at a relatively low level, about 65 meters (210 feet) below the Overlook crater rim, associated with summit deflation. Spattering was active along the lake margins. This photograph shows overflows from April and May (dark lava in bottom portion of photograph) covering the floor of Halema‘uma‘u Crater.

Pele's hair covers the roadside along Crater Rim Drive, next to the Halema‘uma‘u parking lot, in an area of Hawai‘i Volcanoes National Park closed to the public due to proximity to the summit lava lake. The Pele's hair (long strand of volcanic glass) is emitted from the lava lake and carried upwards by the rising gas plume, and then drifts downwind.
