At least one of the hazard maps published in the prominent "El Espectador" newspaper in Bogotá included glaring errors. Without proper graphic scaling, it was unclear how big the map's hazard zones really were. The lahars on the map did not have a distinct ending point, and the main threat seemed to be from pyroclastic flows, not from mudflows. Though the map was colored blue, green, red, and yellow, there was no key to indicate what each color represented, and Armero was located in the green zone (believed to indicate the safest area).
