The threat of an EMP event or Electromagnetic Pulse attack has been brought before Congress as a very real threat to the United States electrical infrastructure. EMP’s have been referenced in movies like Ocean’s 11, the Matrix 2 and Broken Arrow. In addition, fictional books like Going Home and 1 Second After use the concept of an EMP attack as the catalyst to create the collapse of society as we know it. In this article, we’ll discuss 5 things you need to know about EMP’s and we’ll focus on separating fact from fiction.
The knowledge about EMP’s has been around for quite some time. In recent years, it was brought up by both Rick Santorum and Ben Carson in the January 2016 GOP debate as a potential scenario that could happen to the U.S. should such rogue nations such as North Korea or Iran gets nuclear capabilities.
In this article, we’ll discuss these 5 things you should know about an EMP event:
- What is an EMP event?
- Who has this technology?
- What would happen if an EMP attack were launched against the U.S.?
- How probable is an EMP attack against the U.S.?
- What can be done to prepare for an EMP event?
What is an EMP?
Wikipedia defines it like this: An electromagnetic pulse (EMP), also sometimes called a transient electromagnetic disturbance, is a short burst of electromagnetic energy. Such a pulse’s origination may be a natural occurrence or man-made and can occur as a radiated, electric or magnetic field or a conducted electrical current, depending on the source. EMP interference is generally disruptive or damaging to electronic equipment, and at higher energy levels a powerful EMP event such as a lightning strike can damage physical objects such as buildings and aircraft structures.
OK, so what does that matter to you?
The key concern with EMP’s is the effect it has on electronics and our electrical grid. The electrical grid in the United States is not capable of handling a large-scale EMP or Coronal Mass Ejection, or CME which I’ll talk more about in just a moment. It would take time to recover from such an event as electronic equipment used to control generating units would have to be replaced. Such spare parts are not normally carried in volume in a power plant for wholesale circuit board replacement. In the case of the electrical transformers for a power grid, the length and intensity of the EMP or CME would be the overriding concern as to whether critical damage to the equipment occurred. The grid is hardened for lightning strikes, but not for a large CME or EMP’s. There’s been CME’s in the last 20 years and Canada normally bears the brunt of the problem due to their proximity to the northern pole.
The concern with an EMP is that if one were used over a city or region, it would possibly destroy all electronics which are not hardened. The word possibly is used as so many factors must come together for an EMP to be a real threat. The distance of travel for an EMP is normally line of sight, however, due to the effects on a power grid, it can travel through a grid to the furthest point of the grid, which could be many miles from the event itself. The effects of an EMP were actually experienced on the island of Oahu in Hawaii, shortly after 11 p.m. on July 9, 1962. It was at this time that a thermonuclear weapon was tested over the Johnston Atoll and the subsequent EMP destroyed around 300 street lights in Oahu.
During an EMP, there’re 3 types of pulses that are emitted. There’s an E1, E2, and E3 pulse. I won’t go into a lot of detail about these 3 types of pulses, but suffice it to say they damage electronics and would do a lot of damage to the electrical infrastructure.
Another natural phenomenon similar to an EMP is a CME or Coronal Mass Ejection. A CME is a giant cloud of solar plasma (think of a tremendous surge of several terawatts or even potentially more) with its associated magnetic field that has been blown away from the Sun during strong, long-duration solar flares and filament eruptions. In this article, we’ll focus on EMP’s but many of the effects of a CME could have the same impact as an EMP.
So who has this EMP technology?
Well, technically the countries that possess nuclear weapons have this capability. There are eight sovereign states that have successfully detonated nuclear weapons. Five are considered to be “nuclear-weapon states” or NWS under the terms of the Treaty on the Non-Proliferation of Nuclear Weapons, or NPT. In order of acquisition of nuclear weapons, these are the United States, the Russian Federation, the United Kingdom, France, and China. Since the NPT entered into force in 1970, three states that were not parties to the Treaty have conducted nuclear tests: India, Pakistan, and North Korea. Israel is also widely presumed to have nuclear weapons, though it maintains a policy of deliberate ambiguity regarding this, and is has not been proven definitively to have conducted a nuclear test nor has any acknowledgment been made by Israel of such an occurrence.
While there are additional options to deliver an EMP without nuclear weapons, their capabilities are minimal.
What would happen if an EMP weapon were used against the U.S.?
As a nation, we have experienced technological leaps and bounds over the last few decades and our infrastructure has become more and more reliant on these technologies. Farms can now produce crops at 40x the yield that they could just 100 years ago due to the advancements in equipment (both mechanical and electronic derived), pesticides and fertilizers. Our power production facilities have become very dependent on computers to run many of the systems as well and are dependent on these modern technologies as we’ve moved away from the old analog systems. If the electrical infrastructure were to be crippled or completely destroyed, the results would be devastating. Everything you take for granted on a daily basis: food delivery, trucking, sewage, internet, cell phones are all dependent on these systems working. At the moment, very little has been done to harden these systems against any manmade type of EMP or CME. For nations wishing to inflict a large scale impact on our nation, an EMP weapon would have a profound impact on our nation. While the military has taken steps to harden their equipment against such an event, very little has been done in the civilian population to ensure the equipment that runs the critical infrastructure is protected. If our entire infrastructure were compromised, the systems in place to keep us alive would fail and the recovery could take a significant amount of time, potentially years.
What would a successful EMP attack look like? I would recommend you read The EMP Commission. In the report, it provides a very detailed breakdown of an EMP, its impact to our infrastructure and what the country needs to do to prepare against this threat. It’s a good read, even if you just want to skim through it.
How far would an EMP strike set us back? Depending on which report you read, the expectation is that 90% of the U.S. population would die within the first 12 to 24 months if the entire grid were to go down. That’s something to strongly consider.
How probable is an EMP?
OK, so we’ve discussed a lot of the doom and gloom of EMP’s, so let’s discuss the probability we’ll see an EMP strike on our nation’s soil.
In May of 2015, Peter Pry warned congress that this type of attack on American soil would kill approximately 9 out of 10 people through starvation, disease and societal collapse. In his scenario, an EMP resulting from a high-altitude nuclear detonation, while possible is not very probable. If someone bent on hurting us were to pull this off, they would need a ballistic missile and nuclear weapons. The missile would need to be an Intercontinental ballistic missile that was launched from their soil or they’d need to have a platform that was within range of the U.S., similar to the threat during the Cuban Missile Crisis.
The probability that a rogue nation or terrorist group could develop the technology in order to pull this is off is nearly impossible. Why is this? There are 3 primary things that have to be considered:
- It requires a sophisticated rocket capable of lifting a payload of nuclear material that could produce an explosion in the hundreds of kilotons or megatons range, which is a significant amount of weight. The nuclear bombs North Korea has been testing are significantly smaller than this.
- It requires a ballistic missile that can deliver the payload to a very specific place. Too high, and the process of dislodging electrons can’t work. Too low, and the area that’s affected is smaller meaning that it would only affect the city or area it detonated over.
- And it requires a willingness to bear the brunt of the action. If a country like North Korea or Iran were to launch one of these missiles from their country (assuming they could somehow even come up with the technology to pull this off), it would be obvious in a matter of seconds from the time the missile was launched and satellites detected the launch. At which point countermeasures would be taken with appropriate retaliatory measures, meaning they’d be pretty much wiped off the face of the earth.
In one of my favorite fiction novels regarding EMP’s, a book named 1 Second After, the storyline describes nuclear missiles being launched from container ships around the U.S. Again, as we described above, the probability that a terrorist group or rogue nation could amass this technology to build a rocket capable of delivering in the exact spot with hundreds of megatons is highly improbable.
If I were a betting man, I’d put my money on Cyber attacks crippling the U.S. electrical grid. We’re already seeing this happen around various power plants around the U.S. Utilities which have had “cyber incidents” like ransomware attacks according to the National Rural Electric Cooperative Association. These types of incidents are increasing in frequency and could be a greater issue in the future.
What can be done to prepare for an EMP event?
Well, first the grid could be hardened to withstand EMP’s. Conservative numbers to harden the grid could be as little as 3 percent more than existing capital investment for electric grid upgrades which would translate to about 1 to 3 billion per year. There have been many complaints nationwide on how dilapidated our nation’s infrastructure has become and considering how much money we invest in frivolous programs already, in my opinion, this would be money well spent.
You could also build a Faraday cage to house the equipment in. A Faraday cage or Faraday shield is an enclosure used to block electric fields. It is formed by a conductive material or by a mesh of such materials. A Faraday cage operates on the premise of making the external electrical field which causes the electric charges within the cage’s conducting material to be distributed such that they cancel the field’s effect in the cage’s interior. Faraday cages can be made to protect your personal electronics are not that difficult to make. While getting into the specifics of building one of these is beyond the scope of this article, you can easily research online by simply Googling “how to build a faraday cage” and I plan on creating an article specifically for this in the not so distant future.
Hopefully, this article gives you a high-level view of EMP’s. The threat of an EMP has been brought up recently within politics and while the possibility of an EMP strike against our country is possible, it’s not that probable.

Another way I have found that really helps prevent burn out is to teach others what you know. 
Prepping is not a destination but rather a journey. I had this same epiphany years ago with finances when I started reading Dave Ramsey’s book, 
Use your gear and become familiar with it. As you use it, you will gain experience which will lead to confidence. Each time I camped out and went on these mountain climbing expeditions, I began to learn my gear and discovered the things I needed and the things I did not need.
As a team, we were able to break up the gear and help each other out. For example, certain individuals were in charge of carrying certain food or cooking utensils and we’d break up the tent amongst those we were sharing a tent with. In addition, we’d break up tasks amongst the team. Some people were in charge of gathering wood, others were in charge of cooking, some in charge of cleaning, etc. We’d break up the responsibilities and rotate them in the team to avoid one person having to do everything.
When we were on these expeditions, we had guides that would take us up the mountain. The average trip was about 5 days long and during these 5 days, the guides were there to help us make the ascent. For some in our group, this was their first outing into the wilderness and they didn’t have a clue on how to set up a tent, start a fire, etc. While I had done quite a lot of camping in Boy Scouts prior to these expeditions, I still learned a lot from these guides. The key is to stay humble. Nothing is more frustrating than being around a know-it-all as they can’t be taught anything.
I was on a trip with a group climbing a mountain in New Mexico and it was so hot. We were all sweating profusely when a rain storm blew in. I had a cheap rain jacket I put on that didn’t breath and got only more sweaty as a result. Within a short period of time, the temperature dropped quickly while still raining and now we went from hot and sweaty to cold and wet in our rain gear. The next thing I knew, we were experiencing mild hypothermia. We were all shivering out of control and I became mentally confused. Most of us were unable to perform simple tasks, like setting up a rain tarp to get out of the elements. Fortunately, we had 2 guides that realized what was happening and they took control helping us set up our tents, get into our sleeping bags and they heated up water for us all to drink. It took a little time to recover, but it was an experience I still remember until this day.
I’ll never forget the time we were all climbing a mountain and at the end of the first day, this individual began developing blisters badly. She had never worn her boots prior to the trip and her boots were not broken in. As a result, she developed hot spots on her feet which lead to blisters which resulted in a very painful trip for her. Had she not received the proper treatment from our guides, they could have easily gotten infected and it could have gotten much worse from her.
People that complain hurt the whole team. Ever heard the idiom, “A rotten apple spoils the barrel.” I’ll never forget this one trip where we were climbing in New Mexico and things were going just great. We were all having a great time and about 2/3rds of the way through the trip we had this one guy that started complaining. It was infectious and really brought the entire team down. What started as a great trip ended up becoming miserable.
We were doing this ascent up Mount Elbert, which is 14,439 feet in elevation when one of the older gentlemen in our group nearly had a heart attack. This guy had not prepared for the trip and was overweight. We had to practically carry him up the mountain and looking back, we were lucky he survived. I’ve seen this same situation play out on several other expeditions I’ve done. People underestimate the stress that will be involved, neglect their body, and when they need it to perform, it fails them.
This is by far the most important point. Ever heard the term, “loose lips sink ships”? This is an American English idiom meaning “beware of unguarded talk” and was used during WWII to warn soldiers that sharing important information may end up getting into the hands of the enemies. So then who are these individuals that we should not be sharing this information with? Let’s look at a few different people.
Just as with a neighbor, the moment you provide information about your preps to a family member, who all will they tell? They may tell their neighbor that they have a nephew who is a prepper, or they may tell others in their circle of friends, or the conversation may come up with their favorite cashier at a store. You have no control of how that will play out or who learns what about you. You’ve now become compromised. Remember that game we played as kids where we passed information around a group and compared what the final person had to say versus what the original story was? It’s a lot like that. You may innocently share that you have food, water supplies, firearms and medical kits in your home and by the time that information gets out, there’s no telling how many times the story may change and grow to the point where others see your home as a place to go to if there’s a problem.
I was in Salt Lake City recently and drove past a big house that was backed up against the highway. In their backyard, I could see that they had large solar panels along with quite a few 55-gallon blue water drums. They looked like were living off the grid and it appeared they were probably preppers (this is an assumption based on what I was seeing). If things were to go bad and the grid went down, think other individuals in that area would have taken note of this and will probably show up at their door? They looked like they were preparing for something and it was obvious to see. Be conscious of what others see when they drive past your house. Don’t make things obvious.
Also, be conscious of what others see when they visit your home. If you have contractors come into your home, are your preps in full view or do you put things away? Again, remember in our example earlier. Information spreads quickly. So once someone sees something in your home that gets their attention, they’re now going to spread that information to others and you have no control on how that plays out. Think about the UPS driver who drops off that ammunition you purchased online. The boxes often have a description written on the side and they’re probably making a mental note of this. Also, think about when throwing that ammunition box in the trash as now your neighbors will see that box.
So there’s been an event, a catastrophe has occurred and now there’s no electricity and people are running out of food and water. Now what? If you’ve got backup power and people see you with lights on (you’ve got the only house on the block that has lights still), people are going to quickly piece it together that you have resources. If you start cooking food outside on your BBQ grill and others can smell what you’re cooking, guess who’s coming to dinner. This is where you have to use common sense. You need to black out your windows and prepare food inside or at night.
I tend to keep a low profile in regards to my preps with my neighbors and friends. When I first started, I was excited to share with others but I quickly realized for the reasons mentioned above that this is a huge liability. How many of us have shared prepping with others and had gotten this response: “if things get bad, I’ll come to your house.” This is not a scenario you want to encounter because when people get desperate, they’ll do whatever it takes to survive. Practice OPSEC. Keep vital information to yourself and in the event anything happens in your area, you will lessen the likelihood that you and your family become targets.
I would encourage you to get to know people with skillsets that can be useful and cultivate those relationships. I am very fortunate to have friends that are nurses and doctors, gardeners, military personnel and handymen. While most of these people would not consider themselves “preppers”, I’ve been slowly introducing some of them to concepts of emergency preparedness and they have been taking steps to slowly prepare their family. Remember, be patient with people. The goal is to move them down the field. If my friends and family did nothing more than stock a good supply of food and water, that would be huge and would remove a big burden off me if they needed my help.
By the way, trying to force prepping on others and warn them only turns them off. I had a family member that did this years ago and it completely backfired on him and really weirded some family members out. While as preppers we understand the value and wisdom of being prepared for what might lie ahead, you have to lead people by educating them slowly. Some people see the value of preparing right away, but most do not.
