Santa Ana in El Salvador

This false-color image was taken on Feb. 3, 2001, by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA’s Terra satellite. The Santa Ana volcano is on the left side with the flat-topped mound. Further, “a tiny blue spot in the center of the inner-most crater is a crater lake, the likely source of the boiling water flood,” writes NASA. On Oct. 1, 2005, this volcano erupted, spewing ash as high as 8 1/2 miles into the air. The eruption killed two people via landslides in the town of Palo Campana while forcing thousands to evacuate.
