Evacuation

Evacuation refers to a massive planned movement of population from an area perceived as being under threat or for other reasons. Examples include the 2008 evacuation of New Orleans prior to Hurricane Gustav, and the evacuation during the Second World War of children from the major cities of Britain. Following the Russo-Finnish War of 1939-40 the Finnish population was evacuated from the areas ceded to the Soviet Union. Other examples would include the evacuation of the people in the areas surrounding the Chernobyl and Fukushima nuclear plants.
