The iconic white-capped volcano known as Popocatepetl, located less than a two-hour drive from Mexico City, awoke in April after more than a decade of silence.<br /><br />Spurting lava and steam for kilometres, the volcano threatens to dump ash on the more than 25 million people that live within a 100km radius.<br /><br />Scientists say they cannot predict when it will erupt, but the country's Natural Disaster Prevention Centre has increased its alert to the third highest level.<br /><br />Al Jazeera's Rachel Levin reports from Puebla, Mexico.
