The Colombian Red Cross and Civil Defense personnel were the principal first responders to Armeno, participating in and organizing rescue and medical care. The Colombian military also played an important role in the logistics of the rescue activities by providing helicopter airlift for victims in need of medical care, distributing supplies, and establishing field medical care and shelter. After the first 24 hours, resources of all types began to arrive through the joint efforts of the international disaster relief community, and the individual efforts of over 30 foreign countries. Health services administered 80,000 doses of Tetanus and Typhoid injections in order to avoid the spreading of dangerous diseases. There was also numerous long term responses to the Nevado del Ruiz event, starting off with a plan for warning and evacuation in threatened areas in the event of another eruption. This plan outlined planning areas such as identifying hazard zones, population and property census, alert procedures and security in evacuated areas. On a separate note, hazard maps were distributed in towns at risk to illustrated appropriate prospective action in response to hearing sirens. Evacuation route markers were painted on buildings in towns at risk to illustrate proper egress from danger areas if sirens were heard. Mexico may be a middle economically developed country, but their response to the eruption was very unorganized, ineffective, and lacked preparation. Firstly, Mexico did not have a single, designated government organization officially responsible for responding to any natural hazard emergencies. Meaning that no one was particularly prepared for the task. When the El Chichón eruption began, the Mexican Army was put in charge of attending to the crisis. Although the Mexican Army tried to help to the best of their abilities, confusion and uncertainty was very prominent among the citizens and the military. The government officials decided that partial evacuation rather than totale evacuation was the best course of action. So, people did not stay in their homes but were allowed to tend to their crops and their livestock. This means that people were generally not relocated.
