False-colour infrared satellite image of Iceland. The colour coding ranges from white for the coldest parts, through blue & green, to orange & red for the warmest areas. The large white area at bottom right is the enormous Vatnajokull glacier. The other glaciers are the Hofsjokull (centre), Langjokull (centre left), & Myrdalsjokull (lower centre). The red areas are regions of volcanic activity. The image was recorded by NASA's Heat Capacity Mapping Mission satellite in 1980.
