Detailed Description
This thermal map shows the fissure system and lava flows as of 6 am on Tuesday, July 31. The fountain at Fissure 8 remains active, with the lava flow entering the ocean. The dominant ocean entry points were on the section of coastline near Ahalanui. 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.
