Skychart popocatepetl mexico10/29/2022 ![]() ![]() Su forma cnica es casi simtrica, y gracias a su altura (5.500 metros) hay glaciares perennes cerca de la boca del cono. Temido, amado, respetado, pero siempre rodeado de una aureola que distingue a los volcanes. The International Space Station Program supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. El majestuoso volcn Popocatpetl reina desde el centro de Mxico. Was acquired February 16, 2003, with a Kodak 760C digital camera with an 800-mm lens, and is provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Group, Johnson Space Center. This has encouraged the establishment of numerous agricultural fields (visible as faint rectilinear patterns in the lower half of the image) on the eastern flank of the mountain. Despite its close proximity, similar age, and similar geologic character to Popocatepetl, Iztaccíhuatl has not erupted in historic times. Deep valleys have been eroded into the massive apron of ash and pumice deposits, glacial outwash, and alluvium to the east of the volcano. Glaciers and year-round snow are also present on Iztaccíhuatl (white regions along the peaks). In contrast to Popocatepetl’s well-defined symmetrical cone, Iztaccíhuatl is formed from several overlapping smaller cones that trend north-northwest to south-southeast. These can melt during eruptions to form dangerous mudflows that blanket areas to the south. In addition to the constant danger of eruptions producing ash deposits, pyroclastic flows, and lava (see an earlier astronaut photograph of Popocatepetl erupting), the summit of Popocatepetl also hosts glaciers. Popocatepetl has produced small, intermittent eruptions since 1994. The faint plume emanating from Popocatepetl’s 250- to 450-meter-deep summit crater attests to the significant, ever-present hazard the volcano represents to the 25 million people living in the region, including the nearby city of Amecameca, as well as the metropolitan centers of Mexico City to the northwest and Puebla to the east. As part of the circum-Pacific “Ring of Fire,” Mexico hosts several of the world’s most continually active volcanoes, including the massive Popocatepetl (Aztec for “smoking mountain.”) This detailed, oblique astronaut photograph also depicts a neighboring volcano, Iztaccíhuatl (the “Woman in White.”) With North to the right in the scene, the view is a westward-looking perspective. ![]()
