Lava Flow Approaches Royal Gardens Subdivision

This small-scale map shows Kīlauea’s active East Rift Zone lava flow field in relation to the southeastern part of the Island of Hawaiʻi. The area of the active flow field on June 16 is shown in pink, while widening and advancement of the active flow field as mapped on June 23 is shown in red. The area covered by the inactive June 27th flow is shown in orange. The Puʻu ʻŌʻō lava flows erupted prior to June 27, 2014, are shown in gray.

The blue lines over the Puʻu ʻŌʻō flow field are steepest-descent paths calculated from a 2013 digital elevation model (DEM), while the blue lines on the rest of the map are steepest-descent paths calculated from a 1983 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 base map is a partly transparent 1:24,000-scale USGS digital topographic map draped over a 1983 10-m digital elevation model (DEM). (Click to enlarge)

This map shows recent changes to Kīlauea’s active East Rift Zone lava flow field. The areas covered by the recent breakouts at Puʻu ʻŌʻō as of June 16 are shown in pink, while widening and advancement of the active flow as mapped on June 23 is shown in red.

The area covered by the inactive June 27th flow is shown in orange. Puʻu ʻŌʻō lava flows erupted prior to June 27, 2014, are shown in gray. (Click to enlarge)
