Kahaualeʻa 2 Flow Still Expanding North of Puʻu ʻŌʻō – Ocean Entries Remain Active

Hawaii Volcano Observatory Report, 6/28/2013:

The Kahaualeʻa 2 flow remains active north of Puʻu ʻŌʻō, and has expanded a very minor amount into the forest, burning trees.

The flow, which consists of slowly moving pāhoehoe, has widened but advanced little over the past two weeks.

The Kahaualeʻa 2 flow, which is active north of Puʻu ʻŌʻō, is fed from a vent at this cone on the northeast rim of Puʻu ʻŌʻō crater.

Small openings at the top of the cone contain sloshing lava, and two skylights at the very start of the Kahaualeʻa 2 lava tube provided views of a swiftly moving lava stream rushing downslope.

Just inland from the entry point a patch of slightly warmer temperatures indicates an area of recent small breakouts. Inland from this warm patch you can see a narrow line of elevated temperatures that traces the path of the lava tube beneath the surface that is supplying lava to this ocean entry. Two plumes of high temperature water spread out from the entry point.
