A government report analyzed the impact of a ground 10-kiloton explosion in Washington DC. Turns out it wouldn’t be quite as bad as you might think (well, compared to what it would have looked like during the cold war when the scenario was multiple megaton air bursts). The full report contains a number of nice map visualizations of the severe fallout threat. The bad news? I live and work within the “severe damage, lifesaving not likely” region. Oh well…
