>It's not because it's a flattened sphere, the energy directed to the ground gets reflected upwards mostly
It's half a sphere. Just multiply everything by 2.
But you fail to understand what the importance of square law is here. It means that if you scale ALL distances up 2 times, you will need 4 times higher yield to accomplish the same result.
>Not that one, the one you oosted, but simple math, that's talking about 350 nukes on the lower yield side, with an average death estimate of 75 million. That's the entire population of the first 15 or 17 biggest Indian cities.
This one?

Let me stress once more:
>Outside a radius 1km from the ground center, there are almost no damage in a concrete building.
With 100x yield, the same observation will be true for everything 10km from ground zero.
