Small-scale map of June 27th flow in Kīlauea's ERZ

This small-scale map shows the June 27th flow in Kīlauea's East Rift Zone on September 10, 2014. The area of the flow on September 8, 2014, at 12:45 PM is shown in pink, while widening and advancement of the flow as mapped on September 10 at 2:45 PM is shown in red. The front of the active flow was 14.5 km (9.0 miles; straight-line distance) from the vent and 0.6 km (0.4 miles) from the east boundary of the Wao Kele o Puna Forest Reserve. The actual length of the flow, measured along the lava tube axis (so that bends in the flow are considered) is 16.6 km (10.3 miles). The flow was advancing toward the northeast. The blue lines show down-slope paths calculated from a 1983 digital elevation model (DEM). For an explanation of down-slope path calculations, see: http://pubs.usgs.gov/of/2007/1264/. All older Pu‘u ‘Ō‘ō lava flows (1983-2014) are shown in gray; the yellow line marks the lava tube.
