Mount Belinda in the South Sandwich Islands

This false-color image comes from Montagu Island in the South Sandwich Islands, which are located between South America and Antarctica. Mount Belinda was inactive until late 2001, when it began erupting. The image was taken on Sept. 23, 2005, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) riding NASA’s Terra satellite. As NASA describes the image, “red indicates hot areas, blue indicates snow, white indicates steam, and gray indicates volcanic ash.” Steam is sent up in a plume from where the hot lava meets the ocean.
