Lava Now One Mile From Reaching Ocean

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 30 is shown in pink, while widening and advancement of the active flow field as mapped on July 5 is shown in red. Older Puʻu ʻŌʻō lava flows (1983–2016) 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/).

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/). When mapped on Sunday afternoon, the flow front was about 690 m (755 yards) beyond the base of the pali along the western boundary of the abandoned Royal Gardens subdivision; the flow front was about 2.6 km (1.6 miles) from the ocean.

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 the 1983 10-m digital elevation model (DEM).
