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

Breakouts are active in three general areas near Puʻu ʻŌʻō: at the northern base of Puʻu ʻŌʻō, north Kahaualeʻa, and about 6 km (4 mi) northeast of Puʻu ʻŌʻō. The distal breakout and the breakout north of Kahaualeʻa are both burning forest. There is no eruptive activity downslope from the distal breakout (nothing active near Pāhoa).

HVO geologists get fresh lava samples as close to the vent as possible. Once the sample is scooped from the pāhoehoe lobe, it is quickly quenched in a bucket of water to stop the growth of any crystals and to preserve the composition of the liquid lava. Once cooled, the sample is sent first to UH Hilo for quick analysis of a few components and prepared for a fuller analysis of its chemical components by a lab on the mainland. These data are used, with HVO's geophysical monitoring data, as another way to assess any changes that may be occurring within Kīlauea volcano.
