New Thermal Map Shows Fissure System
The U.S. Geological Survey released this thermal map that shows the fissure system and lava flows as of 12:15 p.m. on Monday, May 21, 2018.
The primary lava flows originate from the Fissure 20-22 area. The dominant ocean entry is marked. 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.
