Popocatépetl Volcano Continues to Emit Smoke and Ash

Satellite images captured by Landsat 8 and an astronaut on the International Space Station show ongoing emissions from Mexico's Popocatépetl volcano, which has been erupting since 2005. The images show plumes of water vapor, volcanic gases, and ash rising from the summit crater, with some plumes reaching as high as 7.3 kilometers. The source of another plume between Popocatépetl and the nearby dormant volcano Iztaccihuatl is unclear. The volcanic alert level remains at yellow, the middle level of a three-color scale.
