A video of the flow front moving through vegetation.

This small-scale map shows Kīlauea's active East Rift Zone lava flow field in relation to the southeastern part of the Island of Hawai‘i. The area of the active flow field on June 23 is shown in pink, while widening and advancement of the active flow field as mapped on June 28 is shown in red. Older Pu‘u ‘Ō‘ō lava flows (1983-2016) are shown in gray.

The active lava flow from Pu‘u ‘Ō‘ō was on the slope near the top of the Pūlama pali today, one of the steep escarpments on Kīlauea's southeast flank, and had transitioned into a channelized ‘A‘ā flow. The view is to the northwest.

At the time the photograph was taken, the active lava flow from Pu‘u ‘Ō‘ō was on the slope near the top of the Pūlama pali, one of the steep escarpments on Kīlauea's southeast flank, and had transitioned into a channelized ‘a‘ā flow.

This photo shows a closer view of the front of the ‘A‘ā flow.

This map shows recent changes to Kīlauea's East Rift Zone lava flow field. The area of the active flow field as of June 23 is shown in pink, while widening and advancement of the active flow as mapped on June 28 is shown in red. Older Pu‘u ‘Ō‘ō lava flows (1983-2016) are shown in gray.

Spattering was vigorous in the Kīlauea's summit lava lake this evening, but within the range of normal variation. Spatter was thrown up to the level of the floor of Halema‘uma‘u Crater, about 25 m (80 ft) above the lake surface.

This satellite image was captured on Monday, June 27, by the Advanced Land Imager instrument onboard NASA's Earth Observing 1 satellite.

The lava pond in the western portion of Pu‘u ‘Ō‘ō crater remains active, and has enlarged since our last observation. The pond today was about 50 m (160 ft) in diameter, with spattering along the western margin.

This small-scale map shows Kīlauea's active East Rift Zone lava flow field in relation to the southeastern part of the Island of Hawai‘i. The area of the active flow field on June 16 is shown in pink, while widening and advancement of the active flow field as mapped on June 23 is shown in red. The area covered by the inactive June 27th flow is shown in orange.

This map shows recent changes to Kīlauea's active East Rift Zone lava flow field. The areas covered by the recent breakouts at Pu‘u ‘Ō‘ō as of June 16 are shown in pink, while widening and advancement of the active flow as mapped on June 23 is shown in red. The area covered by the inactive June 27th flow is shown in orange.

The episode 61g flow from Pu‘u ‘Ō‘ō continues advancing downslope. In this photo, the current flow is the lighter color area along the center of the image. The flow front has advanced about 770 m (0.5 miles) since the June 16 overflight, which equates to an advance rate of about 100 m per day (330 ft per day).

Incandescent vents are still open on the northeast flank of Pu‘u ‘Ō‘ō. From the ground, no views of the lava were possible because the area around the vent was too unstable and dangerous to approach.

An aerial view of the same vent shown at left provided a look of the lava stream within the deep cavity.
