Photo and Video Chronology - Kīlauea - October 23, 2015

Scattered breakouts persist northeast of Pu‘u ‘Ō‘ō...

This photo looks west towards the upper East Rift Zone of Kīlauea. The fume-filled crater at Pu‘u ‘Ō‘ō is in the foreground, and the vent for the June 27th lava flow is just out of view of the lower right corner of the photo. Mauna Loa is visible in the upper right.

A hornito was active in the upper portion of the June 27th flow, with hissing and jetting sounds coming from a small opening at the top. The hornito here was about 2.5 m (8 feet) tall. A hornito is formed by gas and lava forced through a small opening in the roof of a lava tube. One side of the hornito has a small solidified flow of lava that oozed from the top, with the remainder consisting of spatter and Pele's hair.

An HVO geologist collects a sample of active lava for chemical analysis. The lava is quenched with water in the metal bucket.

A small channel feeds a lobe of pāhoehoe lava on the eastern margin of the June 27th flow. Scattered breakouts like these were active on the flow field today, with the farthest active lava about 6.4 km (4 miles) from the vent on Pu‘u ‘Ō‘ō.
