MEXICO CITY, Mexico - Mexican authorities on Sunday raised the warning level for the Popocatepetl volcano to one step below red alert, as smoke, ash and molten rock spewed into the sky posing risks to aviation and far-flung communities below.
Volcanic activity from the Popocatepetl volcano led the Mexican government to raise the warning level and to close schools in dozens of municipalities across three states. On Monday, local, state and federal officials held drills for the possibility of evacuations.
