This large-scale map uses a satellite image acquired in March 2014 (provided by Digital Globe) as a base to show the area around the front of Kīlauea’s active East Rift Zone lava flow. The area of the flow on January 13 is shown in pink, while widening and advancement of the flow as determined from satellite imagery on January 17 is shown in red. The most distal portion of the flow on January 17 was approximately 700 meters (0.4 miles) from Highway 130. Overall the activity is sluggish and comprised of scattered breakouts and oozing pāhoehoe toes.

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.
