Look at this. Alex Wellerstein, a historian of science at the Stevens Institute of Technology, developed this NUKEMAP: the map shows the impact of nuclear detonation. NUKEMAP uses Google Maps info: you can select any location in the world. Also you can use presets such as detonations from the past (either pick that location or yield -in kilotons-. Imagine what the Hiroshima explosion would do to your hometown. Impressive to see, plus it is an interesting use of maps to visualise information.
The map screen shots below show:
1. The impact of the Little Boy (used in Hiroshima 70 years ago) on Amsterdam
2. The impact of the W-78 (in the current US arsenal) on New York
