August 9 Thermal map of fissure system and lava flows

This thermal map shows the fissure system and lava flows as of 6 am on Thursday, August 9. 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 was a small, mostly crusted, lava pond (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.
