August 11—Thermal map of fissure system and lava flows

Release Date:

This thermal map shows the fissure system and lava flows as of 6 am on Saturday, August 11.

 

Thermal map of fissure system and lava flows.

Residual lava in the Fissure 8 flow continues to drain, feeding numerous small ocean entries (shown in main map). In the Fissure 8 cone there were two small lava ponds (shown in small inset map). The black and white area is the extent of the thermal map. Temperature in the thermal image is displayed as gray-scale values, with the brightest pixels indicating the hottest areas. The thermal map was constructed by stitching many overlapping oblique thermal images collected by a handheld thermal camera during a helicopter overflight of the flow field. The base is a copyrighted color satellite image (used with permission) provided by Digital Globe.
