In today's world, the threats we face are becoming more sophisticated and potentially devastating. One such threat is an Electromagnetic Pulse (EMP). Understanding what an EMP is and the risks it poses to our modern infrastructure is crucial for national security and personal preparedness. This blog post will delve into the nature of EMPs, their potential impacts, and what we can do to mitigate the risks.
What is an EMP?
An Electromagnetic Pulse (EMP) is a burst of electromagnetic radiation that can disrupt or destroy electronic equipment and electrical systems. EMPs can be natural or man-made.
Natural EMPs are typically caused by solar flares or geomagnetic storms. Man-made EMPs are generated by nuclear explosions at high altitudes or specialized EMP weapons designed to emit powerful bursts of electromagnetic energy.
How EMPs Work
EMPs work by emitting a sudden and intense burst of electromagnetic energy, which travels through the atmosphere and can induce high voltage surges in electronic circuits. This surge can burn out microchips, fry circuits, and render most modern electronics inoperable.
Throughout history, there have been notable EMP events. The Starfish Prime Test in 1962 was a U.S. nuclear test in the Pacific Ocean that generated an EMP, knocking out streetlights and damaging electronics over 900 miles away in Hawaii.
In 1859, a massive solar flare, known as The Carrington Event, disrupted telegraph systems worldwide, causing fires and widespread communication outages.
The Risks of an EMP Attack on the United States
The U.S. power grid is highly vulnerable to an EMP attack. Potential sources of such an attack include state actors, such as China, Russia, North Korea, and Iran as well as rogue nations and terrorist groups.
These adversaries could use an EMP to cause widespread disruption without the need for a traditional military assault.
In 2004, a report of the Commission to Assess the Threat of the United States from Electromagnetic Pulse (EMP) Attack was published.
In this report, the committee determined that “several potential adversaries” have the ability to attack the U.S. with an EMP and produce significant damage to critical infrastructure, and “thus to the very fabric of U.S. society.”
It went on to explain that EMP threats are “difficult to deter—they can be terrorist groups that have no state identity, have only one or a few weapons, and are motivated to attack the U.S without regard for their own safety.” And also that “generally there are neither precursors, nor warning, and no opportunity for human-initiated protective action.”
The Impact of an EMP Attack
An EMP attack on the U.S. could have catastrophic effects. Power grids, communication networks, and electronic devices would fail instantly.
Critical infrastructure, such as transportation, healthcare, and water supply systems, would be severely impacted long term.
Food and water shortages, lack of medical care, and widespread panic could ensue, potentially leading to economic collapse and civil unrest.
Alarmingly, the EMP Commission warned that an attack “could shut down the U.S. electric power grid for an indefinite period, leading to the deaths within a year of up to 90 percent of all Americans.”
Yes, pause and read that again.
Lack of Preparedness
As a result of deregulation in the 1990s, the power industry in the U.S. is now a complex network of around 3,000 electric utility companies. While this led to increased competition in wholesale electricity prices, it also resulted in cost cutting for contingency preparedness. And it presents major challenges for implementing a comprehensive plan.
In fact, the EMP Commission reported that “it is too impractical to protect the entire electrical power system from damage by an EMP attack. There are too many components of too many different types, manufacturers, designs, and vulnerabilities within too many jurisdictional entities, and the cost to retrofit is too great.”
To further illustrate the fragility of the grid, the 2021 Texas power grid crisis was brought on simply by three severe winter storms which lead to the worst energy infrastructure failure in Texas history. Experts warned that the Texas power grid was “seconds or minutes away from” complete failure that could have taken months to restore. More than 4.5 million households were left without power for several days and at least 246 people died as a result.
What Individuals Can Do to Prepare
While government and military efforts are essential, individual preparedness is also crucial. Here are some practical steps that you can take:
- Stockpile essential supplies: Ensure you have enough food, water, and medical supplies to last each member of your family for at least several weeks.
- Backup power solutions: Invest in generators or solar power systems to maintain basic functions during a prolonged power outage.
- Build community resilience: Work with neighbors and local organizations to create a support network in case of an EMP event.
Understanding the threat of an EMP and taking steps to prepare can significantly mitigate the impact of such an event. By staying informed and proactive, we can protect ourselves, our families, and our communities from the potentially devastating effects of an EMP attack.
