You worry about it. I'll worry about a heart attack or getting squashed while driving.
I'm not worried about it. I was merely attempting to render the requested explainations to one I presumed not to know the physics.
In the case of an EMP attack, I'd assume that the EMP producing burst was indended as a prelude to near-ground bursts at optimum altitudes. So, the EMP and its source wouldn't really be the main concern.
Your questions seemed to ask the physical difference between EMP and lightning, not the difference in the probability between being struck by lightning as compared to EMP. Were you baiting for this line of conversation?
