The flow front remains active on the coastal plain, but has only moved about 60 m (~200 ft) closer to the ocean in the past three days.
As of midday on July 15, the slow-moving pahoehoe is roughly 870 m (~0.5 mi) from the ocean. Activity upslope continues to widen the flow margins. The light gray surface in this image is the new pahoehoe of the 61G flow.

This map is a georeferenced thermal image mosaic showing the distribution of active and recently active breakouts on the Pūlama pali and coastal plain. The thermal images were collected during a helicopter overflight on July 15. The episode 61g flow field as mapped on July 8 is outlined in yellow to show how the flow has changed. Most surface flow activity is on the coastal plain, but breakouts also continue on pali.
According to this mornings USGS HVO Lava flow report the flow is now 0.4 miles from the emergency road:
The 61G lava flow, southeast of Puʻu ʻŌʻō remains active on the coastal plain on Kīlauea’s south flank. HVO geologists visited the flow field on Friday. As of midday, the lava flow front was about 730 m (0.4 miles) from the coastal emergency road and 870 m (0.5 miles) from the ocean, an advance of only about 60 m (200 feet) since July 12. The leading tip of the flow was active on Friday and the area around the flow tip has widened. The most vigorous flow activity was nearer the base of the pali and extending out about 1.3 km (0.8 miles) from the base of the pali.
