Each year on 18 April, radio amateurs around the world celebrate World Amateur Radio Day. On that day in 1925 the International Amateur Radio Union was founded.
In 1913 there occurred the first recorded instance of amateur radio being used to provide communications in a natural disaster, during severe flooding in the Midwest of the United States.
Accordingly, the theme of the event for 2013 is Amateur Radio: Entering Its Second Century of Disaster Communications.
Activities on the occasion of World Amateur Radio Day 2013 can be a great opportunity to spread the word about what the hams are doing in the field of disaster communications in the 21st Century.
