DEW attack in Canneto di Caronia?

[ArMaP]

Obviously, I don't know where they got that 10-12 GW power from, but if we make a sudden interruption of the electric current in a wire coil that will create a strong change in the magnetic field, which then createa strong currents on any nearby conductor.

What I mean with that is that the power needed depends on how close those nearby conductors need to be to be affected by that sudden strong current, so I suppose they considered a long distance between the source of the electromagnetic field and the affected objects, which I think is not correct, as a very strong source would create a strong current in all conductive materials in the affected area, and that's not what happened in these cases, in which the fires were localised.
