Ham Radio during Disaster
One of the resolutions taken by the World Administrative Radio Conference, Geneva, in 1979 says that Amateur Radio activity throughout the world should be promoted, because in the event of a natural disaster, normal communication systems are frequently overloaded, damaged or completely disrupted at a time when rapid establishment of communication becomes essential to facilitate worldwide relief actions. Under those circumstances, a greater density and wide-spread distribution of ham radio stations can efficiently assist in meeting the communication needs. Also in the event of a natural disaster, direct communication between amateur radio operators and other wireless stations belonging to the police, armed forces and para-military forces might enable vital communications to be carried out until normal communication are restored.
