Thermal map of fissure system and lava flows

The flow from Fissure 8 continues to advance in a northeast direction and was roughly 7 km (4.3 miles) from the vent at Fissure 8. The front of the Fissure 18 flow has stalled, with activity limited to the area near that vent. 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.
