With a name that means smoking mountain in the Aztec language, Mexico’s Popocatépetl does not disappoint. The towering volcano, about 70 kilometers southeast of Mexico City, was emitting a faint plume of steam and gas on January 4, 2011, when the Advanced Land Imager (ALI) on NASA’s Earth Observing-1 (EO-1) satellite captured this photo-like image.
The agency that monitors volcanoes in Mexico reported five low-intensity eruptions between January 4 and 5. Popocatépetl erupts frequently, and the current eruptive episode started on January 9, 2005, according to the Global Volcanism Program.
