July 14—Thermal map of fissure system and lava flows

July 14, 2018

 

Thermal map of fissure system and lava flows
Only the lower portion of the flow is shown - the upper portion was not imaged today due to weather. The fountain at Fissure 8 remains active, with the lava flow entering the ocean at numerous points in Kapoho. The channel overflow from July 9-10 created a new lobe that has reached the ocean at Ahalanui Park, creating a robust ocean entry plume. 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.
