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

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

Detailed Description

This large-scale map shows the distal part of the June 27th flow in relation to nearby Puna communities. The area of the flow on October 30, 2014, at 12:00 PM is shown in pink, while widening and advancement of the flow as mapped on October 31 at 12:25 PM is shown in red. Surface activity today was scattered from the flow front to about 2.2 kilometers (1.4 miles) upslope of AP‘A‘ā Street. The most persistent breakout was at the 2.2 kilometer (1.4 mile) distance traveling northward. pāhoehoe toes were oozing from a broad front 135 meters (148 yards) across. The blue lines show steepest-descent paths calculated from a 1983 digital elevation model (DEM; for calculation details, see 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.
