The fountain at Fissure 8 remains active, with the lava flow entering the ocean at Kapoho. Very small, short 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.
