The farthest active breakout on the June 27th flow reached about 8 km (5 miles) northeast of the vent on Pu‘u ‘Ō‘ō. The tip of this breakout was narrow and burning forest. Pu‘u ‘Ō‘ō is at the top of the photograph.

Over the past week small flows have filled the bottom of Pu‘u ‘Ō‘ō Crater. These flows originated from vents in the south portion of the crater, and one of the flows can be seen near the center of the photograph.

The Overlook crater lava lake, within Halema‘uma‘u Crater at Kīlauea's summit, has been rising over the past few days, and today reached the highest point yet measured for the current summit eruption. The lava lake this afternoon was 20 meters (66 feet) below the Overlook crater rim.

The lava level was high enough at the lava lake this evening that bits of spatter were reaching the rim of the Overlook crater.

Another view of the lava lake, with several areas of spattering active.

This satellite image was captured on Monday, April 20, 2015 by the Landsat 8 satellite. Although this is a false-color image, the color map has been chosen to mimic what the human eye would expect to see. Bright red pixels depict areas of very high temperatures and show active lava. White areas are clouds.

Active surface flows on the northeast flank of Pu‘u ‘Ō‘ō on March 12, 2015. The activity is a continuation of a breakout that began on February 21, which diverted lava from the tube system and helped to starve the supply of lava to the June 27th flow front near Pāhoa.

This photograph looks upslope and shows another narrow lobe on the breakout that is roughly 6 km (4 miles) northeast of Pu‘u ‘Ō‘ō. This lobe was moving along the south margin of the June 27th flow.

This map shows recent changes to Kīlauea's active East Rift Zone lava flow field. The area of the flow on April 3 is shown in pink, while widening and advancement of the flow as of April 9 is shown in red. We were not able to map some parts of the flow field with breakouts today due to poor weather, and these areas are denoted in boxes.

Breakouts continue northeast of Pu‘u ‘Ō‘ō in three main areas: 1) at the northern base of Pu‘u ‘Ō‘ō cone, 2) north of Pu‘u Kahauale‘a and 3) about 6 km (4 miles) northeast of Pu‘u ‘Ō‘ō. This photograph looks east and shows the breakout about 6 km from Pu‘u ‘Ō‘ō.

A closer look at the leading tip of the farthest downslope breakout. The tip of the breakout was burning forest, and was 6.9 km (4.3 miles) northeast of the June 27th vent on Pu‘u ‘Ō‘ō.

Breakouts remain active in three general areas near Pu‘u ‘Ō‘ō: 1) at the northern base of Pu‘u ‘Ō‘ō, 2) just north of Kahauale‘a, and 3) the most distal breakout, about 6 km (4 miles) northeast of Pu‘u ‘Ō‘ō. This photograph shows much of the most distal breakout, a portion of which was burning forest. Pu‘u ‘Ō‘ō can be seen near the top of the photograph.

The breakout north of Kahauale‘a has one lobe that has traveled along the west side of the perched lava channel that was active in late 2007. This breakout consists of blue glassy pāhoehoe, which is easily visible in the photograph on the left. The white box shows the rough extent of the thermal image on the right.

In the time since our last overflight (March 24), a new collapse pit has formed in the western portion of Pu‘u ‘Ō‘ō Crater. This circular pit can be seen in the lower left portion of the photograph, and measures about 27 m (roughly 90 ft) in diameter. Numerous hot cracks were observed in this general area during previous visits on foot.
