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

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 3, 2014, at 9:20 AM is shown in pink, while widening and advancement of the flow as mapped on October 6 at 12:15 PM is shown in red. Breakouts were mainly scattered across the leading 1.5 km (1 mi) of the flow, and midway along the length of the flow where lava first entered the crack system. A few other breakouts were active on the surface within 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 indicate approximate flow path directions.
