One more thing for disaster junkies to obsess about
Like myself, of course.
A nuclear device detonated at an altitude of a couple hundred miles over the middle of the United States would essentially drop us back into the pre-industrial age. EMP, or electro-magnetic pulse, is a well known effect of high altitude nuclear explosions. The result is that electrical and electronic equipment gets fried. Without electronic and electrical equipment, we have... nothing. Given that over the last fifty years, every article of technology we have has become deeply intertwined with electronics, removing all that juicy, productivity and life enhancing stuff leaves us with what we had in, say, 1800. In 1945, we would have been much safer from EMP, given that most of our industrial infrastructure was mechanical, and not so vulnerable. Now, only the most heavily shielded electronics would survive. The effect will hit even deeply buried electronics, and having something turned off is no protection either, since the pulse naturally effects the wiring - the fact that there is power in it or not is irrelevant.
All ill-intentioned non-denominational agrarian reformers need to commit this perfidy on the peace loving folk of our nation is:
- A nuclear device, available at special terms from the worker's paradise of North Korea,
- A medium range ballistic missile, such as a Scud, of which there are thousands throughout the world,
- A moderately large freighter, to get within a hundred miles or so of the American Coast, and provide a stable launch platform, and
- The aformentioned ill intentions
An attack of this nature could conceivably cause vastly greater casualties than exploding the same device in, say, downtown Manhattan. While the immediate casualties resulting from an EMP blast might be as low as zero, the after-effects would be horrific in the extreme as all of our distribution, communication and power systems are knocked completely out. Imagine New Orleans after Katrina, nationwide. The worst thing about New Orleans was the fact that thanks to its geographical isolation, it was difficult to get aid into the city effectively. When everyone is out, things could get very bad.
The loss of food distribution, in particular, would be the most dire possibility. With vehicles no longer working, food stays in warehouses. And no major city is more than three days from starvation, thanks to the large scale implementation of highly efficient, but fragile just-in-time inventory schemes. Everyone is without power, and the capacities of work crews to fix things would be swiftly overwhelmed. So you have Katrina combined with the great blackout.
One thing that would still work though, is guns. Make of that what you will.

Would transport trucks and
Would transport trucks and trains actually be messed up by EMP? Personal cars would be bad, of course, but as long as we have our main transportation infrastructure up, there's no danger of starvation. Also, would one EMP actually cover the whole continent? It seems like the horizon distance at 200 miles up doesn't even cover that much.
That ballistic missile
That ballistic missile defence project is sounding better and better every day, isn't it.
Just as long as it's able to target missiles which aren't necessarily coming over the horizon...
In fact, Aegis/SM-3 might be able to take down a MRM launched from off the coast if it's detected early enough, I think?
Alsadius, according to the
Alsadius, according to the article and book, a detonation 300 miles up would cover most of the continental US - not unreasonable when you think about it, that's higher than some satellites orbit. Also, anything that kills cars kills trucks just as dead. Even primitive cars have electrical systems, if not computers. Trains likewise, I would assume. These things can be repaired, but there would be a period where almost everything would be out of whack - or at the very least, significant fractions of everything.
As I understand it, EMP, by its nature, generates currents in conductors. That's why its so bad.
Ballistic Missile Defense has always looked good to me, Nicholas, but sure this is one more reason for it. I think you're right, a block three standard missile could do it, but it'd be a toss-up. The land based systems don't have much chance, especially given where they'd be located if they could be made to work. And the airborne laser isn't likely to be in the right place either. The Patriot batteries in Washington wouldn't likely have the range unless the terrorists were fool enough to launch in the Chesapeake.
Another effect would be the
Another effect would be the vaporization of every financial transaction in progress at the moment the weapon detonated. Untold billions of dollars, much of which only exists virtually in the first place, would evaporate.
Keep your receipts. You'll need them in the Afterworld.
And that's with a "standard" fission weapon; imagine the more thorough effects of an electromagnetic weapon designed from the outset to destroy electronics.
Oh, and read Streiber and Kunetka's Warday. A 'small" nuclear war is the setting for the book.
Just read a book posted
Just read a book posted online called Lights Out, with this very premise. I'm thinking about laying in some pre '65 silver.
