The June 27th lava flow remains active. A Civil Defense overflight yesterday at 12:30 pm showed the flow front was still moving in a general northeast direction, bringing it closer to the western boundary of Kaohe Homesteads (which is the eastern boundary of the Wao Kele o Puna forest reserve). The flow front at that time was 14.8 km (9.2 miles) from the vent, measured in a straight line, and 0.3 km (0.2 miles) from the Forest Reserve/Kaohe Homesteads boundary. The actual length of the flow, measured along the lava tube axis (so that bends in the flow are considered) is 16.9 km (10.5 miles). Between September 6 and 10, the flow front advanced at approximately 400 meters (460 yards) per day. Between September 10 and 11 the advance rate dropped slightly to approximately 300 meters (330 yards) per day. 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 Pu?u ????, 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 as they creep into the adjacent forest.
