Shaded-relief map of ERZ near flow front

Detailed Description

This shaded-relief map, courtesy of the Carnegie Airborne Observatory, shows some of the cracks, faults, and grabens (down-dropped blocks between adjacent faults; http://earthquake.usgs.gov/learn/glossary/?term=graben) that are present in Kīlauea's East Rift Zone, and which have partly controlled the June 27th flow's advance direction. The June 27th flow as of September 6 is shown in pink, while flow advance since then (as of ~12:45 PM on September 8) is partly transparent and shown in red. At the time of the mapping, the flow was advancing toward the north, and its front was at the location of the last obvious east-northeast-trending structure visible on the map.
