For example, here's the potential fatality toll if a W-87 nuclear weapon was detonated in my home city of Sydney, Australia.

Over 6.4 million fatalities.
This interactive site is based on NUKEMAP, a site developed by Alex Wellerstein, an assistant professor of science and technology studies at the Stevens Institute of Technology. The numbers are calculated using this model.
Terrifying stuff.
