Pu‘u ‘Ō‘ō and the northern lava flow
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.

Pu‘u ‘Ō‘ō — Active Lava Flow
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.

Multiple lava streams entering ocean, and breakouts near base of pali
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.

Mauna Ulu—an opportunity to study a long-lived rift zone eruption
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.

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.

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

Ocean entry and coastal plain surface flows remain active
The ocean entry near Kupapa`u Point remains active, with numerous streams of lava entering the water over a wide section of coastline.

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.

Lava continues to overflow Pu‘u ‘Ō‘ō's eastern rim
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.

Ocean entry near Kupapa‘u Point
Activity at the ocean entry near Kupapa‘u Point has increased slightly over the past several days, with small entry points now spread along the coastline on both sides of the National Park boundary. Whale watching season has also arrived—the splash of whitewater near the bottom center part of the photo is from a breaching whale investigating the ocean entry.

Kīlauea's current eruption is a natural laboratory for volcanologists
Tephra falling from a lava fountain on September 6, 1983, helped build the Pu‘u ‘Ō‘ō cone, which eventually reached a maximum height of 255 m (835 ft) in 1986.

Lava lake in Halema‘uma‘u Overlook vent
The lava lake in the Overlook vent reached to within 40 m (130 ft) of the Halema‘uma‘u crater floor before sunrise this morning, before beginning to drop again. The lake level, however, remains high, as can be seen in this photo, looking west. Note the dramatic overhang on the north-northwest side of the vent (to the right).
