Thermal map of fissure system and lava flows

The flow from Fissure 8 crossed Highway 132 yesterday. The Fissure 8 flow front today was near Noni Farms Road during the noon overflight. In addition, Fissure 18 was producing a narrow channelized flow with the flow front 0.9 km (0.6 miles) from Highway 137. 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.
