Large-scale map of June 27th flow in Kīlauea's East Rift Zone...

Detailed Description

This large-scale map shows the June 27th lava flow in Kīlauea's East Rift Zone in relation to nearby Puna communities. The area of the flow on November 17, 2014, at 2:00 PM is shown in pink, while widening and advancement of the flow as mapped on November 24 at 12:00 PM is shown in red. This afternoon there were lots of breakouts in the region of the distal crack(s) SW of Kaohe and close to the old well site. Today's activity consisted of pāhoehoe flows that are expanding the margins of the crack flows and also feeding a series of pāhoehoe lobes and breakouts that are moving downslope along the western margin of the first Pāhoa flow. Burning vegetation and smoke marks the advance of the pāhoehoe flows in the rainforest. Upslope there were a few tiny breakouts above where the tube enters the crack system. The blue lines show steepest-descent paths calculated from a 1983 digital elevation model (DEM; for calculation details, see http://pubs.usgs.gov/of/2007/1264/). Steepest-descent path analysis is based on the assumption that the DEM perfectly represents the earth's surface. DEMs, however, are not perfect, so the blue lines on this map can be used to infer only approximate flow paths. All older Pu‘u ‘Ō‘ō lava flows (1983-2014) are shown in gray; the yellow line marks the recently active lava tube.
