A large EM pulse is bad because when they move orthoganally accross a wire
they induce a current down that wire. This current won't necessarily go in
the direction the wire was mean to carry current. And it may be larger
than the amount of current the wire was meant to be able to withstand. 

But there is something you can do about it.

Just surround your house with a Farraday(sp?) cage.
Get alot of tin foil.
Wrap it around your house.
Make sure it's grounded well (try attaching it to your lightning rod).

Now when the EM pulse hits the tin foil it will be turned into current.
The current will drain into the ground. And the EM pulse will not continue
on its way through your house.
