El Popocatépetl Continues to Emit Molten Rock and Ash
A cloud of ash and molten rock spews out of Popocatépetl volcano, about 35 miles from Mexico City, on May 20.
Mexican authorities raised the alert level to “Yellow Phase Three,” the fifth of a seven-stage warning system. More than 20 million people from the states of Puebla, Tlaxcala, Morelos, State of Mexico and DF would be affected if “El Popo” erupted.
The word Popocatépetl means Smoking Mountain in Nahuatl.
