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 area of the flow on November 12 and 13 is shown in pink, while widening and advancement of the flow as mapped on November 14 at 1:40 PM is shown in red. Surface activity continues along the north margin of the flow between 230 meters (250 yards) upslope of the flow tip and 2.7 kilometers (1.7 miles) mauka of AP‘A‘ā Street. The most active flow over the past few days is approximately 230 meters (250 yards) from AP‘A‘ā Street. Also, above where the flow enters the crack there was a small breakout 260 meters (285 yards) in length along the flow margin. 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.
