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. The latitude and longitude of the most-active, slowly advancing breakout on September 24 was 19.473080, -154.981264 (Decimal degrees; WGS84). 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.
