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

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 24, 2014, at 12:10 PM is shown in pink, while widening and advancement of the flow as mapped on October 29 at 11:30 AM is shown in red. Surface activity today was scattered from the flow front to about 4 kilometers (2.5 miles) upslope, where breakouts have been persisted for several weeks across the surface and along the sides of the flow field, before it necks down into the finger now advancing toward Pāhoa Village Road. A few other breakouts were active farther upslope, west of Kaohe Homesteads, and a single small breakout was active on the flow field about 5 kilometers (3 miles) downslope from the vent.

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.
