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