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 15, 2014, at 10:30 AM is shown in pink, while widening and advancement of the flow as mapped on October 17 at 7:40 AM is shown in red. Breakouts were scattered across the leading 1.9 km (1.2 mi) of the flow, and there were a few small breakouts mid-way along the length of the flow where lava first entered the crack system. The black dots mark the flow front on specific dates. 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.
