The June 27th lava flow remains active and continues advancing towards the northeast. Recently, the flow front entered the Kaohe Homesteads subdivision, and is currently within the vacant, forested northwest portion of the subdivision. The flow front was 3.3 km (2.1 miles) upslope from Apa‘a Road and 4.3 km (2.7 miles) from Pāhoa Village Road.

An HVO geologist conducts a very-low frequency (VLF) survey of the lava tube to measure the rate of lava flowing through the tube. The measurement consists of two steps. First, a transect of VLF measurements across the roof of the tube is used to measure the cross-sectional area of lava flowing through the tube.

As of Friday afternoon, September 12, 2014, the most distal front of the June 27th lava flow had reached a straight-line distance of 14.9 km (9.3 miles) from the source vent on the northeast flank of the Pu‘u ‘Ō‘ō cone.

Several HVO scientists participated in a series of public meetings in Pāhoa and nearby communities when the June 27th lava flow, named for the date in 2014 that the flow started, threatened to inundate part of the Puna District, including houses, businesses, roads, and utilities.
