Hawaii Volcanoes Observatory Update

No activity was observed on the Peace Day flow on today’s overflight, meaning that the Kahaualeʻa 2 flow is now the sole active flow.

The Kahaualeʻa 2 flow today had reached 6.4 km (4.0 miles) northeast of Puʻu ʻŌʻō, and was burning vegetation around the forest boundary.

Much of the Kahaualeʻa 2 flow has traveled over ʻaʻā from Puʻu ʻŌʻō’s early activity in the 1980s.

This photo shows a lobe of the Kahaualeʻa 2 flow advancing over a section of this older ʻaʻā, burning moss and small trees that have grown on the ʻaʻā clinker.

Active pāhoehoe breakouts are scattered across portions of the Kahaualeʻa 2 flow.

This photo shows a nice example of ropy pāhoehoe active near the flow margin.

Very few surface flows have been observed in Puʻu ʻŌʻō crater over the past month, but the crater today was far from quiet.

The spatter cone shown here, in the northern portion of the crater, was producing a loud, continuous jetting sound resulting from gas being forced through a tiny opening at the peak.
