The lava flow fed the northeastern lava lake in Pu‘u ‘Ō‘ō remains weakly active at the northern base of the Pu‘u ‘Ō‘ō cone. The front of the flow is burning lichen on old ‘A‘ā flows erupted from Pu‘u ‘Ō‘ō during 1983-1986. The eastern edge of Pu‘u ‘Ō‘ō is at the upper right side of the photo.

This photo, identical to the previous one, just includes labels for the flows that spilled from the northern and southern sides of the crater.

Several streams of lava were entering the water near Kupapa`u Point. Here at the eastern end of the ocean entry a narrow stream is battered by the surf.

Breakouts near the shoreline have diminished over the past week, but surface flows remain active closer to the base of the pali on the coastal plain.

A small pāhoehoe lobe flows into a crack on the coastal plain.

As this pāhoehoe lobe flows into the crack, the surface layer rolls up creating a ropy texture that is common on pāhoehoe flows.

The ocean entry near Kupapa`u Point remains active, with numerous streams of lava entering the water over a wide section of coastline.

A portion of this pāhoehoe flow is channeled into a crack by two surrounding tumuli.

Only a few scattered breakouts were active near the shoreline, with most of the activity on the coastal plain closer to the base of the pali. This pāhoehoe lobe was active near the east margin of the Peace Day flow field just a few hundred meters (yards) from the coastline.

A surge of "blue glassy" pāhoehoe flows out of an inflated flow margin near the shoreline. This type of lava is thought to be stored within an inflating flow for up to a few days, changing its color and texture.

Eruptive activity in Pu‘u ‘Ō‘ō has picked up over the past week. Lava flows erupting sporadically from several places continue to fill the crater and occasionally spill out onto the east flank of Pu‘u ‘Ō‘ō. This view, looking southwest, shows new lava from active and recent flows on Pu‘u ‘Ō‘ō's eastern flank.

This photo, looking south, shows lava spilling from the small, perched lava lake on the northeast side of Pu‘u ‘Ō‘ō's crater floor. The rim on the east side of the crater, in the background, has been nearly completely buried and is no longer discernable.
