Southeast of Mexico City, Mexico
|About 40 miles (65 km) southeast of Mexico City is the volcano called Popocatepetl, nicknamed Popo, with a summit 17,930 ft (5,465 m) high. Popo, located in the center of the right side of this Landsat 7 image, has a gray appearance because of volcanic ash, in contrast to the snow-covered mountain to the north. The metropolitan area of Mexico City, with 20 million people, is the light gray region in the upper left corner of the image. Popo experienced a large eruption 1,200 years ago and there have been occasional smaller eruptions since.
