There was a city 60 miles from the tsar bomb and it has all its windows and doors blown in . People vastly exaggerate nukes and always compare them to the Hiroshima bomb ,yeah it was 6000 times more powerfull or something like that but the doesn't mean 6000 times more damage .
The device tested was 50Mt I was referring to the theoretical 100Mt - plus test configuration was different to how it would be utilised in a real attack.
But yeah most people vastly exaggerate the power of a single nuclear device (not to underestimate them either).
