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 10 at 10:45 AM is shown in pink, while widening and advancement of the flow as mapped on November 12 at 7:00 AM is shown in red. Surface activity occurred along the north margin of the flow between 400 meters (437 yards) upslope of the flow tip and 2.2 kilometers (1.4 miles) mauka of AP‘A‘ā Street. A breakout has moved along AP‘A‘ā Street, onto a property makai of AP‘A‘ā Street and continued 270 meters (295 yards) farther northeast. Another breakout has moved within the fence of the Transfer Station. A breakout 760 meters (831 yards) mauka of AP‘A‘ā Street has continued to move northeastward and reached 375 meters (410 yards) mauka of AP‘A‘ā Street. Also, there were two distinct, though small, breakouts along the flow margin above the crack system. 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.
