Think of the Nuclear EMP. Lightning does the same. It can create a 
rapidly changing electromagnetic pulse from the current transfer.
And this electromagnetic pulse can create surge voltages in nearby 
conductors.
This is some of the what the various surge protectors guard against.

And as said earlier, lightning rods and such may be enough to bleed off 
charge preventing a build up.

As for a direct lightning strike: there are lots of joules at play.
