Lava Flow Update – Flow Advances About 300 Yards in About 6 Hours

The June 27th lava flow remains active. An HVO flight early in the afternoon yesterday found that the flow had advanced ~280 m (~300 yards) north since a Civil Defense flight just after sunrise that morning (a span of ~6 hours), and the flow front had reached a large crack marked on the topographic base map (but not visible from the air). There was no evidence that the flow was entering this crack, if it exists.

A Civil Defense overflight this morning found that the flow front had advanced an additional 370 meters (400 yards) since yesterday afternoon. This puts the tip of the flow at 14.0 km (8.7 miles) from the vent, measured in a straight line, and 1.1 km (0.7 miles) from the Forest Reserve boundary.

The actual length of the flow, measured along the lava tube axis (so that bends in the flow are considered) is 16.0 km (9.9 miles). The flow front is still in thick forest, creating smoke plumes as it engulfs trees and other vegetation, but fires are not spreading away from the flow.

Small breakouts also remain active closer to Puʻu ʻŌʻō, roughly midway along the length of the June 27th flow. None of these breakouts have been very vigorous recently, but are also producing smoke plumes a they creep into the adjacent forest.
