Skip to comments.Life After An EMP Attack: No Power, No Food, No Transportation, No Banking And No Internet

Most Americans do not know this, but a single EMP attack could potentially wipe out most of the electronics in the United States and instantly send this nation back to the 1800s. If a nuclear bomb was exploded high enough in the atmosphere over the middle part of the country, the electromagnetic pulse would fry electronic devices from coast to coast. The damage would be millions of times worse than 9/11. Just imagine a world where nobody has power, most cars will not start, the Internet has been fried, the financial system is offline indefinitely, nobody can make any phone calls and virtually all commerce across the entire country is brought to a complete stop. A nation that does not know how to live without technology would be almost entirely stripped of it at that point. Yes, this could really happen. An EMP attack is America's "Achilles heel", and everyone around the world knows it. It is only a matter of time before someone uses an EMP weapon against us, and at this point we are pretty much completely unprepared.

I just meant that a strike can be made without a full blown ballist missle.
My position has always been that EMP big or EMP effect small the terror and confusion created woukld be as bad or worse than the EMP effect itself.
Yes the damage would more and likely be ‘fixable’, but imagine the LA/SD or the BosNYWash corridor without power for 60 to 90 days? What kind of chaos would result?
EMP blast radius is line of sight. So areas behind mountains might be more protected than those which are not.
The map in question takes into account the curvature of the earth.
Iran currently has missiles with a range of 2500km able to carry a 1 ton payload. Those certainly won’t reach the high orbital altitude but are a threat.
Currently reports have them orbiting a 65kg payload into orbit.
yeah and a coup would make us less of a target /s
Or they can get their hands on one of these:
Just them turning off the power and turning it back on blew several tranformers. That was supposed to have been in a controlled manner.
Let the east and west coasts wake up tomorrow without working iPhones and see what happens.
I see your point.
But who knows the mind of a terrorist? Not me.
Yeah those saudi’s are dirt poor.
What would happen if an EMP hit near the Tennessee Valley Authority?
A few summers ago, our tv cable was constantly messed up. The company swore it was solar flares. I don’t know if they were cya but if true then it’s something to think about.
Yes, I want a galvenized garbage can since the neighbors stole ours (and the brand new never used garden rake) but being on a budget I was thinking of what I had on hand already.
“What are the consequences of EMP or severe solar storm on these devices? It is theorized, but I don’t believe that is known.”
It’s important to clear up this confusion. A Solar EMP is very low frequency - geomagnetic in nature. There is no danger to electronics directly from the solar storm EMP.
But, that’s not the end of the story. Solar Storm EMP manifests itself as a DC current on power transmission lines. This DC offset, if significant enough causes transformers to saturate their ferromagnetic cores every half-cycle. One of the effects of this is the imposition of apparent reactive load on a power system - to compensate, a system may switch on capacitor banks. They may switch the on and off repeatedly as they try to compensate - this can cause significant out-of-spec voltage spikes on power systems that can damage electronics.
If the transformer saturation is really bad, they will quickly overheat and potentially go “boom”. This can also have potentially bad effects on connected electronics downstream from that transformer.
For a nuclear EMP, The military standards have been developed with solid state devices in mind. They recommend a 10,000 fold EMP reduction in most frequency ranges.
Honestly, I can’t say. Any facility or home will be affected in one way or another. Mostly inconvenience or bad in some cases. Think of what wires do. They convey energy of some sort. If that energy is increased to the point of conductor failure, (degradation of wiring insulation or melting the conductor) well something is going to happen. It doesn’t matter the size of the conductor.
I met one of our fine WI state troopers out on the road early this morning. I couldn’t see him but I knew he was there. My radar detector went nuts. The radar sets in their cruisers operate at a power of 1-3 watts of directed radar microwave energy, (If I remember correctly). Imagine/hypothetically that the microwave energy going up to say 100-300 watts. It might not burn out my radar detector but I know the amout of energy has increased because my detector is screaming at me. Move up to 1000 watts and on and on. Then instead of a radar detector, direct that energy to a conductor. Something will happen eventually. EMP/Carrington event = orders of magnitude greater than a troopers radar gun.
Now, we directed microwave energy/EMP/solar flare to a conductor wasn’t designed to carry alot of energy (Cable TV signals/low voltage). When the conductor “picks up” that higher energy, it will degrade the signal to your TV and most likely will fry them both.
In the case of your cable getting squirrelly, IDUNNO. Most cable TV signals travel on coax cable that is shielded from external interference. If there is a bad connection or broken shielding anywhere in the cable run it will cause interference. High voltage power lines (at 5k-12k volts,higher EMF radiation) sometimes run near cable tv coax on the poles. Look at your power poles on the street. Did the cable TV crew replace the coaxial cable run when you had the signal interference?
On the solar flare/storm side, an S4 or S5 solar storm that hits the earth directly (NOAA spaceweather.gov), we won’t be watching much TV. A solar event like we recently experienced didn’t do much to us terrestrials. I believe they affected some satelites and data repeater facilities.
TVA? As before, if it has a wire connected to it or electronics control it. Assume Zap. The nuke plants, they have systems that are designed with fail safes and back-ups galore. I’m not a nuke operator and haven’t been around them much. I do not know if they have “hardened” control systems or “hardened “ back-ups for emergencies. I do know they can scramble the reactor pretty quickly and I have read most newer nukes can cool themselves down without any external power. If someone can expand on that information i’d be interested in knowing.
We do not have “hardened” control systems at the facility I operate. If the electric grid goes down, I can’t generate either. That and a lack of fuel (NG in my case).
