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 30 at 2:30 PM is shown in pink, while widening and advancement of the flow as mapped on January 6 at 11:30 AM is shown in red. Most surface activity was concentrated along the leading 3 km (2 miles) of the flow, but other breakouts were active just north of the True/Mid-Pacific geothermal well pad.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.
