Ash and smoke spewed from Popocatepetl Volcano are seen from Santiago Xalitxintla, in the Mexican central state of Puebla, on April 20, 2012. Residents of nearby communities reported roaring noises from the Popocatepetl volcano near Mexico City after signs of increased activity prompted authorities to raise alert levels.
