Scattered breakouts northeast of Puʻu ʻŌʻō, but little forward progress
Active pāhoehoe lava is scattered over a broad area northeast of Puʻu ʻŌʻō, but has not advanced significantly over the past month. Today, the farthest active lava was about 7.5 km (4.7 miles) from the vent on Puʻu ʻŌʻō, with the leading tip of this breakout burning vegetation. Aerial view towards the southwest. Puʻu ʻŌʻō is in the upper left.
Left: A closer look at the upper June 27th flow field, where numerous breakouts were active. The active breakouts are visible as the light-colored areas near the bottom of the photo. In the lower right, the remains of Puʻu Kahaualeʻa can be seen. Puʻu ʻŌʻō is in the upper left. Right: A view of the southern portion of Puʻu ʻŌʻō crater, where two small incandescent vents have been active recently.
Left: A closer view of the one of the pāhoehoe breakouts near Puʻu Kahaualeʻa. The dark flakes on the surface are bits of crust from the underlying flow that get stuck to the front of the newer flow, and end up on the top surface as the nose of the new flow inflates.

Scattered breakouts northeast of Puʻu ʻŌʻō, but little forward advancement
Scattered breakouts remain active northeast of Puʻu ʻŌʻō on the June 27th lava flow, but have not advanced significantly over the past month. This photo shows the farthest reach of active lava on the flow field today, which was about 8 km (5 miles) northeast of the vent on Puʻu ʻŌʻō. Minor brush fires were active where lava was entering forest.
Left: This photograph shows the south margin of the June 27th flow, northeast of Puʻu ʻŌʻō, where many small scattered breakouts were active. The active, and recently active, breakouts are visible at the light gray areas. Right: Little has changed in Puʻu ʻŌʻō over the past month, and a small lava pond still exists within the circular pit in the western portion of the crater. This pit can be seen through the fume in this photo, and a tiny area of incandescence at the edge of the active pond is barely visible.

Summit lava lake well below Overlook crater rim
One month ago the summit lava lake was at the rim of the Overlook crater (the small crater in the center of the photo), spilling lava onto the floor of Halemaʻumaʻu Crater (the larger crater that fills much of the photo), creating the dark flows surrounding the Overlook crater. Since that time the lava lake has dropped, associated with summit deflation, and today the lake level was about 60 meters (200 feet) below the Overlook crater rim. The stack of recent overflows is visible on the wall of the Overlook crater as the layer of dark lava atop the older, light colored lava forming the majority of the Overlook crater wall.
The photo is taken from the southeast rim of Halemaʻumaʻu Crater. The closed Halemaʻumaʻu overlook is in the upper left corner of the photo. Jaggar Museum and HVO can be seen as a small bump on the horizon in the upper right portion of the photograph.

Scattered breakouts northeast of Puʻu ʻŌʻō
Scattered breakouts remain active northeast of Puʻu ʻŌʻō. On today's overflight, breakouts were active as far as 8 km (5 miles) northeast of Puʻu ʻŌʻō. Some of this activity was at the forest boundary, burning vegetation. This narrow lobe, one of several active on the flow field today, traveled over earlier Puʻu ʻŌʻō lava (light brown) to reach the forest boundary.
Activity at Puʻu ʻŌʻō remains relatively steady. This photograph looks towards the southwest, and shows outgassing from numerous areas in Puʻu ʻŌʻō crater. On the far side of the crater, the small circular pit (right of center) had a small lava pond that was too deep to see from this angle.
Left: As shown in the May 21 field photos, the small forested cone of Puʻu Kahaualeʻa has been slowly buried by flows over the past several months. All that remains today are narrow portions of the rim standing above the lava. Right: Recent lava on the June 27th flow cascaded over the overhanging rim of this collapse pit on an earlier portion of the flow field.
Summit activity continues in Halemaʻumaʻu

Mauna Loa is in the distance. Right: Halemaʻumaʻu Crater, looking west. The dark area on the crater floor consists of recent overflows from the Overlook crater. The Overlook crater is near the left edge of the photo, and a portion of the active lava lake surface can be seen below the rim.

Puʻu Kahaualeʻa nearly gone; lava flow intersects old tube
Puʻu Kahaualeʻa has been buried slowly by the Puʻu ʻŌʻō eruption over the years, and the ongoing June 27th flow has nearly finished the job. The image on the left shows Puʻu Kahaualeʻa on June 30, 2014, a few days after the June 27th flow started (the ʻaʻā flow just behind the cone is from the early stages of that flow); the image on the right shows Puʻu Kahaualeʻa today (May 21, 2015) from nearly the same perspective. Only the highest parts of Puʻu Kahaualeʻa's twin craters remain.
The most distant active tip of the June 27th flow, visible at the left edge of the photo, was about 8.5 km (~5.3 miles) from Puʻu ʻŌʻō today. This lobe of the flow intersected an old lava tube earlier in the week that transported lava a short distance downslope, where it emerged from skylights to make several small isolated pads of lava (center of the photo). The view is to the southwest, so Puʻu ʻŌʻō is well off in the distance beyond the top of the photo.

Kīlauea summit vent lava lake continues to drop
Kīlauea Volcano's summit lava lake continued to drop today (May 15, 2015). Measurements of the lake surface late this afternoon showed that it was 62 m (203 ft) below the top of the newly-created vent rim, a ridge (or levee) of solidified lava about 8 m (26 ft) thick that accumulated on top of the Halemaʻumaʻu Crater floor from multiple overflows of the vent during the past two weeks.

Webcam images capture lava veneer falling into summit lava lake
This sequence of HVO webcam images of Kīlauea Volcano's summit vent, recorded between 1:28 and 1:32 p.m., HST, on May 12, 2015, captures the moment a section of the dark-colored "bathtub ring" (a veneer of fresh lava that coats the vent wall as the lava lake level drops) fell into the lava lake (center). The lava veneer collapse, which produced a visible cloud of rock and lava fragments, agitated the lava lake surface and exposed lighter-colored layers of older rock in the vent wall (right).

Lava lake in Halemaʻumaʻu Crater drops with summit deflation
The summit lava lake in Halemaʻumaʻu Crater has dropped significantly over the past two days, as Kīlauea's summit has deflated. The dropping lava level has allowed lava veneer on the walls of the Overlook crater to fall away, clearly exposing the contact between the original rim of the Overlook crater (which is the original, pre-overflow floor of Halemaʻumaʻu Crater) and the stack of recent lava overflows. These overflows are roughly 8 meters (26 feet) thick in total.

Summit lava lake in Halemaʻumaʻu Crater remains at high level
The lava lake in the Overlook crater, within Halemaʻumaʻu Crater at Kīlauea's summit, remains at a high level and close to the Overlook crater rim. Overflows onto the Halemaʻumaʻu Crater floor have built up the rim of the Overlook crater several meters, and recent overflows are visible in the right side of the photograph. The lake level this afternoon was about 7 meters (yards) above the original (pre-overflow) floor of Halemaʻumaʻu Crater. Spattering was vigorous today in the southern portion of the lake. From this view, the spattering was hidden behind a portion of the Halemaʻumaʻu Crater wall, but airborne spatter can be seen in the bottom left portion of the photo. The summit of Mauna Loa can be seen in the upper right.
This Quicktime movie shows spattering at the margin of the summit lava lake in Halemaʻumaʻu Crater. Spattering has been common at the lake, and when it occurs is easily visible from the public viewing area at Jaggar Museum. This video shows a closer view from the rim of Halemaʻumaʻu, which is closed to the public due to volcanic hazards.

Breakouts continue northeast of Puʻu ʻŌʻō
The June 27th lava flow remains active, with breakouts focused in several areas northeast of Puʻu ʻŌʻō. The farthest downslope activity observed on today's overflight was roughly 8 km (5 miles) northeast of Puʻu ʻŌʻō. This photograph shows one of the active breakouts closer to Puʻu ʻŌʻō.

Summit lava lake in Halemaʻumaʻu Crater remains at high level
Over the past week, the summit lava lake in the Overlook crater rose and spilled out onto the floor of Halemaʻumaʻu Crater, creating the dark flows in the south part of Halemaʻumaʻu (left side of crater from this direction). The extent of the lake itself, set within the Overlook crater, is slightly difficult to distinguish from this view but the spattering at the lake margin is visible. The overflows onto the Halemaʻumaʻu Crater floor, not counting the area of the lake itself, total about 11 hectares (28 acres).
Left: A closer look at the lava lake and overflows on the floor of Halemaʻumaʻu Crater. The outline of the Overlook crater, and the active lake, is easier to distinguish in this view. Right: From this angle, the extent of the lava lake within the Overlook crater is much easier to distinguish from the surrounding overflows. The closed Halemaʻumaʻu parking lot is in the right side of the photograph.
