Geoffrey said that the explosion would wipe out all of Magnolia. So unless he was lying, someone disarms the trap or someone pulls a Yamamoto and absorbs the explosion it will hit all of them to some degree.

But I can't really imagine that the entire town will be wiped out. They have more than enough rebuilding to do as it is.
