The eastern rim of Pu‘u ‘Ō‘ō is no longer visible, having been buried by flows mostly from the small lava lake on the northeast side of the crater floor. A mound of lava with a complex of spatter cones, visible in the background, now surrounds the lava lake, which is only visible from the air.

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

Lava flows have spilled from Pu‘u ‘Ō‘ō crater over the past few weeks. One flow went out the southern end of the crater and traveled a short distance downslope to the southeast before stopping.

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.

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.

A lava fountain during the opening episode of the Mauna Ulu eruption feeds lava flows that cover Chain of Craters Road. Both ‘Ālo‘i Crater (lower left) and ‘Alae Crater (upper right) were filled with lava later in the eruption. Photo taken on May 28, 1969.

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.
