Expert Warns: Civilian World Not Ready For Massive EMP-Caused Blackout

schwit1 (797399) writes "An electromagnetic pulse is a burst of electromagnetic energy strong enough to disable, and even destroy, nearby electronic devices. In the first few minutes of an EMP, nearly half a million people would die. That's the worst-case scenario that author William R. Forstchen estimated would be the result of an EMP on the electric grid. 'If you do a smart plan — the Congressional EMP Commission estimated that you could protect the whole country for about $2 billion,' Peter Vincent Pry, executive director of the Task Force on National and Homeland Security and director of the U.S. Nuclear Strategy Forum, told Watchdog.org. 'That's what we give away in foreign aid to Pakistan every year.' He said the more officials plan, the lower the estimated cost gets. 'The problem is not the technology,' Pry said. 'We know how to protect against it. It's not the money, it doesn't cost that much. The problem is the politics. It always seems to be the politics that gets in the way.'"

      Experts: Civilians not ready for EMP-caused blackout

      On multiple occasions during the past 155 years, large enough CME’s have disrupted electrical systems on Earth. One of the largest recorded solar flares happened in 1859. The CME, called the Carrington Event, disrupted telegraph systems in Europe and North America, and lit up the evening sky.

      A solar flare in 1989 caused a blackout in Quebec that lasted more than nine hours, and systems as far away as New Jersey were also damaged. In 2013, Space.com ranked the solar storm that caused the blackout as the fourth worst in history.

      Space.com ranked a solar storm in December 2006 as the worst, and U.S. government officials reported that the event disrupted satellite communications and GPS signals for about 10 minutes and damaged the satellite that took the picture of the storm.

      A joint study published in 2013 by researchers at Lloyd’s of London and Atmospheric and Environmental Research found that a similar event today would cost the world economy $2.3 trillion.

      Risk of another Carrington-class solar flare is expected to peak by early 2015. In the summer of 2012, Earth narrowly missed one estimated to have been more powerful than the Carrington Event and 35 times the size of Earth.

Automobiles of these vintages include extensive electronics and represent a significant fraction of automobiles on the road today. The testing was conducted by exposing running and nonrunning automobiles to sequentially increasing EMP field intensities. If anomalous response (either temporary or permanent) was observed, the testing of that particular automobile was stopped. If no anomalous response was observed, the testing was continued up to the field intensity limits of the simulation capability (approximately 50 kV/m). Automobiles were subjected to EMP environments under both engine turned off and engine turned on conditions. No effects were subsequently observed in those automobiles that were not turned on during EMP exposure. The most serious effect observed on running automobiles was that the motors in three cars stopped at field strengths of approximately 30 kV/m or above. In an actual EMP exposure, these vehicles would glide to a stop and require the driver to restart them. Electronics in the dashboard of one automobile were damaged and required repair. Other effects were relatively minor. . Twenty-five automobiles exhibited malfunctions that could be considered only a nuisance (e.g., blinking dashboard lights) and did not require driver intervention to correct. Eight of the 37 cars tested did not exhibit any anomalous response. Based on these test results, we expect few automobile effects at EMP field levels below 25 kV/m. Approximately 10 percent or more of the automobiles exposed to higher field levels may experience serious EMP effects, including engine stall, that require driver intervention to correct. We further expect that at least two out of three automobiles on the road will manifest some nuisance response at these higher field levels. The serious malfunctions could trigger car crashes on U.S. highways; the nuisance malfunctions could exacerbate this condition. The ultimate result of automobile EMP exposure could be triggered crashes that damage many more vehicles than are damaged by the EMP, the consequent loss of life, and multiple injuries.

      You've just stated you completely fail to understand the nature of EMP. The most dangerous EMP event is a large nuclear warhead exploded high above the ground, too high to do any meaningful damage on the ground. The damage is caused by the electromagnetic radiation released from the blast as EMP. It only takes one explosion. That isn't a nuclear Armageddon. It is returning a major post-industrial computer based society to a horse and wagon based economy in seconds, without having the horses and wagons to do the work not to mention the computers, computer controlled vehicles (engines), and other electronics.

      Having watched Dark Angel I used to think a hydrogen bomb could do that kind of damage. But AFAIK the biggest man-made EMP ever to damage a city was caused by Starfish Prime. It was a 1.44 megaton H-bomb detonated high in the atmosphere, which caused damage in Hawaii, 1,445 kilometres (898 mi) away. The power didn't go out, though, and the damage was limited. Clearly, the EMP from an H-bomb is bad for electronics, but I doubt there's any way that a single bomb of realistic size could knock the entire United States back to a "horse and wagon based economy".

      You have to ask: if someone wants to attack with an H-bomb, what is more likely: that they would use it as a normal bomb to kill people, or as an EMP to knock out power and damage electronics in less than a 1000-mile radius? Given the seemingly limited devastation (and the need for a rocket in addition to the bomb itself), I think terrorists would surely choose option one. I imagine option two might be considered as part of a World War 3, in which case the aggressor might well use several bombs, and EMPs could be just the beginning of our worries: "I know not with what weapons World War III will be fought, but World War IV will be fought with sticks and stones."

      There is another source of EMP that could be more devastating than any single man-made bomb: see the Carrington Event.

  29. Just don't let cupboards go bare ... by perpenso · · Score: 3, Informative

    After all, you can never be too careful, right?

    Do you realize what careful is? For example when living in earthquake country believing that three days of supplies as recommended by the government is optimistic. So you buy three cases (adjust for family size) of bottled water rather than one, and as you use one case through normal activity you replace it so you always have 2-3 on hand. For your cupboard you purchase six cans (adjust for family size) of a particular canned good you use, when you get down to three you purchase three more, that way you always have 3-6 on hand. Do so each for canned chile, soup, peaches ... whatever you normally use. Similar story with dry goods, 1-2 boxes on hand, snack foods, etc. 1-2 packages of toilet paper. 1-2 boxes of plastic garbage bags on hand, toilet liners if water is out. 1-2 packages of batteries for some LED flashlights. A basic first aid kit with antiseptic, gauzes, tape, bandaids, aspirin/tylenol, etc; no wilderness self-surgery kit necessary. If a disaster occurs eat what is in your refrigerator first, then your freezer, then your canned goods. You can have a week or two of food just by not letting your cupboard go bare. Nothing special or exotic needed, no freeze dried food good for years necessary. No special gear beyond what a boy scout might take on a weekend camping trip is necessary.

    Pretty much all you need is the stuff you normally buy and use anyway. You just don't let inventories get to zero.

  30. Why would we want to defend against EMP? by userw014 · · Score: 2
    (Ignoring the farcical nature of Foxnews...)

    Why would we want someone able to deploy an EMP capable nuclear device to go instead with a dirty bomb or use it to cause more physical damage (i.e.: city-busting?)

    Would defending against EMP like this also defend against a solar coronal mass ejection (like http://en.wikipedia.org/wiki/S... ?) If it can't be justified for an event like that, I don't see the point.
