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 October 6, 2014, at 12:15 PM is shown in pink, while advancement of the flow as mapped on October 8 at 10:20 AM is shown in red. The latitude and longitude of the flow front at that time was 19.48107, -154.96857 (Decimal degrees; WGS84). All older Pu‘u ‘Ō‘ō lava flows (1983-2014) are shown in gray; the yellow line marks the lava tube. 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 indicate approximate flow path directions.
