May 15 A cloud of ash belches out of Mexico’s Popocatepetl volcano, some 35 miles from Mexico City, in the Mexican central state of Puebla.

Authorities have raised the alert level to “Yellow Phase Three,” the fifth of a seven-stage warning system, restricting access to an area of seven miles around the volcano while preparing evacuation routes and shelters.
