Bombing raids during WWII sent out shockwaves powerful enough to alter the Earth's ionosphere

Re: Other explosives

Which also makes me wonder how large an effect Buncefield, Pepcon or Enschede would have had, compared to the average bombing raid

A Lancaster could drop a total of 14,000 pounds, although in practice when bombing cities they tended to be mostly one big (4000lbs) bomb to blow the roofs off and then 10,000 pounds of incendiaries. There were quite a few thousand bomber raids, to a lazy calculation of every aircraft being a lancaster would give you 14000000 pounds, which is ~6.3 kilotons. Pepcon was about 1 kiloton.

But this is very large numbers of smallish explosions compared to one bigish one. I suspect the propagation on the blast waves of a bigger explosion has more of an effect.
