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

Detailed Description

This small-scale map shows the June 27th lava flow in Kīlauea's East Rift Zone in relation to lower Puna. 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 the bulk of the activity was in the region of the distal East Rift Zone crack system, near the old geothermal well site, and downslope. As lava issues from the distal crack region, pāhoehoe flows are moving downslope, parallel to, and west of, the previous Pāhoa flow. 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.
