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 Puʻu ʻŌʻō cone. The flow has continued in the northeast direction that it assumed in the middle of the week and is now only 171 meters (0.1 miles) from the boundary of the Kaohe Homesteads community. The flow is still within thick forest, so that dense plumes of smoke are created as vegetation is consumed. Small breakouts (visible as plumes in the middle distance) are also active closer to Puʻu ʻŌʻō, roughly midway along the length of the June 27th flow. Photo courtesy of USGS/HVO

This shaded-relief map, with digital surface data provided by the Carnegie Airborne Observatory, shows some of the cracks, faults, and grabens (down-dropped blocks between adjacent faults; http://earthquake.usgs.gov/learn/glossary/?term=graben) that are present in Kīlauea’s East Rift Zone, and which have partly controlled the June 27th flow’s advance direction. The June 27th flow as of September 8, 2014, at 12:45 PM is shown in pink, while flow advance since then (as of ~2:45 PM on September 10) is shown in red. At the time of the mapping, the flow was advancing toward the northeast.

This thermal image looks west at the June 27th flow front. The active tip of the flow is at the right side of the image, moving north. Lava issued from several spots along a deep ground crack, which has been traced with the dotted line in the left portion of the image. In addition, lava was filling another crack, also marked, closer to the active tip of the flow. Photo courtesy of USGS/HVO
