The following images and videos come from the USGS Hawaiian Volcano Observatory, located in Hawaii Volcanoes National Park.
Lava falls formed at a topographic break in slope near the eastern base of Pu‘u ‘Ō‘ō. The cascade is about 6 m (20 ft) high.
Lava channel fed by September 21 fissure eruption coursing down the east flank of Pu‘u ‘Ō‘ō.
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.
Close-up view of the lava channel on the relatively steep slope of Pu‘u ‘Ō‘ō’s east flank.
Stalled terminus of the ‘a‘ā flow fed by the September 21 fissure eruption.
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.
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.
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.
