Local police recruited a peasant who lived in the area to supervise 'Don Goyo' As part of his work, he updates a daily photograph of Popocatepetl. Despite the scientific instruments installed on the volcano, experts still require their services.
"A machine is never going to measure the human perception of danger," says one of the technicians at the National Center for Disaster Prevention. The volcano is now 70 years old and the volcano to which he has dedicated his life is in Amarillo Phase 3.
