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. The lava flow field is partly obscured by clouds, but the image shows much of the activity on the June 27th flow. There have been three areas of breakouts active on the June 27th flow recently. The breakout on the north flank of Puʻu ʻŌʻō is obscured by clouds, but the breakout north of Kahaualeʻa is visible through patchy clouds in this image. This breakout has been active recently at the forest boundary, triggering small brush fires. The farthest breakout is about 6 km (4 miles) northeast of Puʻu ʻŌʻō, and consists of scattered activity at the forest boundary.

In the time since our last overflight (March 24), a new collapse pit has formed in the western portion of Puʻu ʻŌʻō 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. Photo taken Friday, April 3, 2015 courtesy of USGS/HVO
