A close-up of the active pāhoehoe flows.

Map showing the extent of lava flows erupted during Kīlauea's ongoing east rift zone eruption. The areas covered during distinct eruptive phases are shown in unique colors and labeled with the years in which those flows were active.

This photo, looking west, shows the current flows that have erupted on the east side of Pu‘u ‘Ō‘ō cone. Pu‘u ‘Ō‘ō cone is the large fume source in the upper left portion of the photograph, and the current flows are sourced from a fissure extending down its upper east flank. In the left-center of the photograph, the bright patch of lava is active pahoehoe.

Map showing the current configuration of Pu‘u ‘Ō‘ō. Old lava flows are shown in colors that match those in the small scale map. The area in dark reddish brown represents the crater-filling lava and overflows of Episode 61 spanning the period from August 20 to September 21.

Close-up view of the lava channel on the relatively steep slope of Pu‘u ‘Ō‘ō's east flank.

Lava falls formed at a topographic break in slope near the eastern base o Pu‘u ‘Ō‘ō. The cascade is about 6 m (20 ft) high.

A new fissure opened and began erupting on the east flank of Pu‘u ‘Ō‘ō early this morning, feeding channelized ‘A‘ā flow. The fissure—the source of the lava flow—is shown in this image. Pu‘u ‘Ō‘ō cone and crater is in the background. View is to the southwest

Close-up aerial view of the head of the erupting fissure. The edge of Pu‘u ‘Ō‘ō crater is at lower right. View is to the east.

Lava channel fed by September 21 fissure eruption coursing down the east flank of Pu‘u ‘Ō‘ō.

View looking east-northeast, directly down the upper end of the fissure. The fuming cones in the foreground are parts of the fissure that erupted when the fissure opened but have since shut down. The spatter beyond, where the fissure is still erupting, is reaching about 2 m (7 ft) into the air. The lava channel is visible in the background.

Pu‘u ‘Ō‘ō cone, and the erupting fissure, is just to the left of top center. The channelized flow initially heads east-northeast, then turns to the southeast. The front of the flow is at the bottom of the image, where it is advancing as an ‘A‘ā flow.

This view is to the east, looking at the western-most erupting part of the fissure. This lava joins with lava erupting from the fissure out of sight below and feeds into the channelized flow visible crossing the through the background of the photo.

Stalled terminus of the ‘A‘ā flow fed by the September 21 fissure eruption.

High aerial view of the active lava channel. The lowest, eastern-most end of the fissure is in view at the bottom of the photo. Rather than feeding the ‘A‘ā flow active for the first couple of days, the flow now is spreading out on the low slope area at the eastern base of Pu‘u ‘Ō‘ō, visible in the top half of the photo.

Lava cascades down the east flank of Pu‘u ‘Ō‘ō cone from a fissure that opened on the upper east flank early Wednesday morning.

A new fissure eruption in September 2011 on the east flank of Pu‘u ‘Ō‘ō on Kīlauea Volcano's east rift zone reminds us of the need to be aware of our ever-changing volcanic environment on Hawai‘i Island. The fissure—the source of the lava flow—is shown in this image. Pu‘u ‘Ō‘ō cone and crater are in the background. Aerial view is to the southwest.

Steaming to the deployment site south of Martha's Vineyard, MA in 2011. The platform shown was specially adapted so the arm cycles up and down through the Benthic Boubdary Layer while deployed on the seafloor.  For more information see https://soundwaves.usgs.gov/2011/11/fieldwork2.html.

The overflows were fed from the edge of an active lava lake filling the east side of Pu‘u ‘Ō‘ō crater. As the lake and its containing levees has risen, an ever increasing amount of the east rim of the crater is being buried. This photo, looking roughly northwest, shows lava overflowing the east rim of the crater.

This photo shows an overflow from the northwest side of the West Gap pit advancing as a narrow channelized flow. The flow is just beginning to transition into ‘A‘ā at its terminus. The view is to the south-southeast.

A lava lake also fills the western side of the crater. This morning, lava overflowed that lake, and then filled and overtopped the northwest rim of a pit on the west side of the crater (the West Gap pit; just above and to the right side of the photo). These flows have traveled up to about 400 m down the northwest flank of Pu‘u ‘Ō‘ō to its base.
