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

Large-scale map of June 27th flow in Kīlauea's East Rift Zone...

Detailed Description

This large-scale map shows the distal part of the June 27th flow in relation to nearby Puna communities. The black dots mark the flow front on specific dates. Small breakouts were scattered across the surface of the flow upslope from the stalled front. Several breakouts were also active midway along the length of the flow near where lava first entered the crack system. The blue lines show down-slope paths calculated from a 1983 digital elevation model (DEM; for calculation details, see http://pubs.usgs.gov/of/2007/1264/). Down-slope 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 indicate approximate flow path directions.
