July 6—Thermal map of fissure system and lava flows

July 6, 2018
Thermal map of fissure system and lava flows
The fountain at Fissure 8 remains active, with the lava flow entering the ocean at Kapoho. Small flows were observed today near Fissure 22. 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.
