View of breakout on northeast flank of Pu‘u ‘Ō‘ō. The light-colored flows in the foreground are active pāhoehoe flows. The view is to the southeast. Pu‘u ‘Ō‘ō is at upper right.

View of recent breakout on east flank of Pu‘u ‘Ō‘ō. The flow has advanced about 1.3 km (0.8 miles), but activity today was focused in the middle part of the flow, closer to its vent. The view is to the west.

Pu‘u ‘Ō‘ō's current crater subsided by about 10 m (33 ft) in the days following the May 24 breakouts. This view, looking southeast, shows the crater as it was today. HVO webcams are perched on the edge of the Pu‘u ‘Ō‘ō cone (an older crater rim) in the foreground.

Overnight on May 13-14, a new spatter cone, shown here, grew over a vent high on the northeast rim of Pu‘u ‘Ō‘ō. HVO scientists for scale.

A close-up view of the spatter cone.

The ground around the spatter cone was covered in small gobs of spatter and Pele's hair, as shown here.

This photo, looking southwest, shows Pu‘u ‘Ō‘ō in the background, with the northern breakout from May 24 extending to the right, with fume coming from a newly forming tube. The feature in the center foreground is a perched lava pond that formed in July 2014, but was refilled by new lava from the northern breakout in recent days.

This is another view of the breakout on the east flank of Pu‘u ‘Ō‘ō. It forms the lighter-colored surface in the lower left quadrant of the photo. Note the orange speck on the breakout - this is the skylight shown in the adjacent photos and the video below.

A closer view of the skylight on the east breakout. The skylight is about 6 m (20 ft) across, and the lava stream is traveling toward the upper right side of the photo.

An even closer view of the skylight (about 6 m or 20 ft across). Again, the lava stream is flowing to the upper right.

The 1887 lava flow erupted from Mauna Loa's Southwest Rift Zone crossed the government road (about a 1,000 feet south of today's Highway 11), traveling 14 km (9 mi) in less than 9 hours. Photo by J.J. Williams, courtesy of National Park Service.

The photo was taken from a vantage looking up Avalanche Gulch at Red Banks (a line of cliffs along the ridge central to the photograph).

The two new flows that broke out on the flanks of the Pu‘u ‘Ō‘ō cone on Kīlauea Volcano's East Rift Zone on May 24 remained active early this morning. The flows were spreading laterally near the vent, but making little forward progress; as a result, they were not posing a threat to any community.

The summit lava lake in Halema‘uma‘u Crater was at a high level earlier in the week, and partly visible from the Jaggar Museum Overlook at times. But over the past few days, the lake level has dropped slightly.

A wider view of the lava lake within the Overlook crater, from the rim of Halema‘uma‘u Crater (closed to the public due to hazardous conditions). Two spattering areas were active, one along the north margin and another in the southeast corner of the lake.

A closer look at the northern spatter source, which spanned roughly 30 meters (100 feet) of the lake margin.

As of 8:30 a.m., HST, today, May 25, 2016, lava continued to flow from two breakout sites on the flanks of the Pu‘u ‘Ō‘ō cone, which was shrouded by rain and steam during HVO's morning overflight.

The two breakouts that began at Pu‘u ‘Ō‘ō yesterday (May 24) are still active. This morning, the active portions of both flows remained relatively short, extending no more than 1 km (0.6 miles) from their breakout points.

This morning (May 25, 2016), the northern breakout on Pu‘u ‘Ō‘ō was feeding an impressive channel of lava that extended about 950 m (0.6 mi) northwest of the cone. This channel was about 10 m (32 ft) wide as of 8:30 a.m., HST.
