I was seeing how big/fast an asteroid that hits New York would have to be to hurt me in Boston. Turns out it would have to be larger than I thought.
Would be nice to be able to click a place on the map and see how survivable that location is.
Did the same on my area with that infamous nuclear bomb simulator/map. Some of the historical warheads seem surprisingly weak relative to modern city sizes. That said, in both nuclear and asteroid impact scenarios, do consider that, while you may be out of range of the thermal and pressure waves, you might still be in range of "extreme disruption caused by survivors closer to the blast moving outwards, emergency services moving inwards, and the economy and social order going to shitters as the country deals with what happened" wave.
