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

This large-scale map shows the distal part of Kīlauea's active East Rift Zone lava flow in relation to nearby Puna communities. The area of the flow on December 19 at 8:30 AM is shown in pink, while advancement of the flow as mapped on December 22 at 3:00 PM is shown in red.
The leading tip of the flow had slowed, but had also widened and split into two branches. The southern branch has stalled while the northern branch continues to advance downslope toward the Pāhoa Marketplace, and the closest was about 675 meters (738 yards) away. Other breakouts were active between about 2.0-3.0 km (1.2-1.9 miles) behind the tip of the flow and about 8.0 kilometers (5 miles) along the northern side of the crack system near the True/Mid-Pacific geothermal well site.
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. The yellow line marks the mapped extent of the active lava tube.
