The fountain at Fissure 8 remains active, with the lava flow entering the ocean at Kapoho. Very small, short flows have been active near the Fissure 6 and Fissure 16/18 area. 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. The base is a copyrighted color satellite image (used with permission) provided by Digital Globe.
