Shaded-relief map of ERZ near flow front

Shaded-relief map of East Rift Zone 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 KÄ«lauea's East Rift Zone, and which are partly controlling the June 27th flow's advance direction. They are not old lava channels. The June 27th flow as of September 3 is shown in pink, while flow advance since then (as of ~11:10 AM on September 6) is partly transparent and shown in red. At the time of the mapping, the flow had mostly filled a ground crack (which extended to the west and was steaming) and was advancing toward the north.
