    Good advice, MMan. I think most of us have read it. Skyowl posted his mudwrestling thread after reading it. He'd already done most of the research. Since he spent 24 years doing military intelligence (hey now, no jokes!), he was already twigged to the possibility of an EMP strike.

    Chinese missles launched off the Western (and Eastern?) seaboard tend to bring this back to the surface of everyone's minds, I suspect.

    Apologies in advance .... my listening skills aren't what they ought to be. It seems that on a daily basis there is brief mention of a terrorist nuke detonation .... I don't recall who the speaker was but he was associated with the dhs .... So be expecting it .... I suspect it'll be a Jericho.

    O.W.

    Aye, good stuff!

    SkyOwl says you do have to insulate the stuff inside, too.

    Now, I'd think that you'd have to keep whatever is inside away from the inside of the metal of the trashcan. Skyowl would know, I'll ask him.
    Yes, I meant to imply that modern vehicles will have issues. Yes, items stored in a FC should be insulated from the metal for complete EMP protection. Good stuff... LH

    No horse is too dead to beat…

    Originally I answered RA’s first question as a “no”, it does not matter if the device is on or off. Since then, as I have continued to delve into the almost sci-fi world of Coronal Mass Ejections (CME) I have learned different, and how a CME event differs from an EMP event. With electronics, an EMP should cook everything that is not shielded, period (that is the planning assumption). With a CME, the odds are very good that if the device is not connected to the power grid or is turned off (not in stand-by) it will still function. In other words, cars that are running will stop, but cars that were parked will start fine. Both an EMP and a CME will fry the main electrical grid system, mostly beyond physical repair; it would have to be completely replaced, re-built from scratch. Anyone have anything significantly different? Bottom line here is that a CME is different from an EMP. I have attached some additional good info on CME below… interesting comments on the early warning satellites at the end… does anyone know someone who actually works in power plant operations and can independently confirm this? Would be nice to know.

    Good website to stay on top of “space” weather.

    Coronal Mass Ejections Can Cause Grid Failure

    A coronal mass ejection (CME) is an ejection of material from the solar corona. They occur when a large bubble of plasma escapes the sun's gravitational field and travels through space to the earth at high speeds over the course of several hours.
    The ejected plasma consists primarily of electrons and protons (in addition to small quantities of heavier elements such as helium, oxygen, and iron), plus the entraining coronal magnetic field.
    Plasma is essentially electrically charged (ionized) gas, consisting of free-moving electrons and ions (atoms that have lost electrons). On earth, we are familiar with the ordinary states of matter: solids, liquids and gases. But in the universe at large, plasma is by far the most common form. Plasma in the stars and the space between them makes up 99 percent of the visible universe.

    Corona

    The corona (as opposed to "a Corona" - a popular Mexican beer) is the outermost layer of the Sun's atmosphere. It extends millions of kilometers into space, most easily seen during a total solar eclipse, but also observable in a coronagraph. The Latin root of the word corona means crown.
    Coronal Mass Ejections were once thought to be the result of solar flares, but while they sometimes accompany solar flares, there is no direct relation between the two.

    Solar Storms

    Coronal Mass Ejections are often called "solar storms" or "space storms" in the popular media. Coronal mass ejections cause shock waves in the thin plasma of the heliosphere, launching electromagnetic waves and accelerating particles (mostly protons and electrons) to form showers of ionizing radiation that precede the CME.
    When a CME impacts the Earth's magnetosphere, it temporarily deforms the Earth's magnetic field, changing the direction of compass needles and inducing large electrical ground currents in Earth itself; this is called a geomagnetic storm and it is a global phenomenon.
    Coronal Mass Ejections impacts can induce magnetic reconnection in Earth's magnetotail (the midnight side of the magnetosphere); this launches protons and electrons downward toward Earth's atmosphere, where they form the aurora.

    Magnetic Storms

    A geomagnetic storm is a temporary disturbance of the Earth's magnetosphere caused by solar coronal mass ejections, coronal holes (the fast-moving component of the solar wind is known to travel along open magnetic field lines that pass through coronal holes), or solar flares.
    A geomagnetic storm is caused by a solar wind shock wave which typically strikes the Earth's magnetic field 24 to 36 hours after the event. This only happens if the shock wave travels in a direction toward Earth.
    The solar wind pressure on the magnetosphere will increase or decrease depending on the Sun's activity. These solar wind pressure changes modify the electric currents in the ionosphere. Magnetic storms usually last 24 to 48 hours, but some may last for many days.

    Recorded Problems

    From August 28 until September 2, 1859, numerous sunspots and solar flares were observed on the sun, the largest flare occurring on September 1st. A massive coronal mass ejection headed directly at Earth due to the solar flare and made it within eighteen hours — a trip that normally takes three to four days.
    On September 1 – 2, the largest recorded geomagnetic storm occurred, as recorded by the Colaba observatory near Bombay, India. There are records in Boston that the light was so bright that even at 1:00 AM it was possible to read a newspaper without any other source of light.
    The combination of the Solar Flare and Coronal Mass Ejection caused a geomagnetic storm that created strong enough currents in certain long Telegraph (then about 15 years old) wires in both the United States and Europe experienced induced emf, in some cases even shocking telegraph operators and causing fires.
    Auroras were seen as far south as Hawaii, Mexico, Cuba, and Italy - phenomena usually only seen near the poles. This was the 1859 solar superstorm.
    On March 13, 1989 a severe geomagnetic storm caused the collapse of the Hydro-Québec power grid in a matter of seconds as equipment protection relays tripped in a cascading sequence of events. Six million people were left without power for nine hours, with significant economic loss. The storm even caused auroras as far south as Texas. The geomagnetic storm causing this event was itself the result of a coronal mass ejection, ejected from the Sun on March 9, 1989.
    In August 1989, another storm affected microchips, leading to a halt of all trading on Toronto's stock market.
    Since 1989, power companies in North America, the UK, Northern Europe and elsewhere evaluated the risks of geomagnetically induced currents (GIC) and developed mitigation strategies.
    Since 1995, geomagnetic storms and solar flares have been monitored from the Solar and Heliospheric Observatory (SOHO) joint-NASA-European Space Agency satellite.
    On February 26, 2008 the magnetic fields erupted inside the magnetotail, releasing about 1015 Joules of energy. The blast launched two gigantic clouds of protons and electrons, one toward Earth and one away from Earth. The Earth-directed cloud crashed into the planet below, sparking vivid auroras in Canada and Alaska.

    Electric grid

    When magnetic fields move about in the vicinity of a conductor such as a wire, a geomagnetically induced current is produced in the conductor. This happens on a grand scale during geomagnetic storms (the same mechanism also influences telephone / telegraph lines and above ground piping (think the Alaskan pipeline)) on all long transmission lines. Fiber optic lines and underground cables are not affected.
    Power companies, which operate long transmission lines (many kilometers in length), are thus subject to damage by this effect. Notably, this chiefly includes operators in China, North America, and Australia; the European grid consists mainly of shorter transmission cables, which are less vulnerable to damage.
    The (nearly direct) currents induced in these lines from geomagnetic storms are harmful to electrical transmission equipment, especially generators and transformers — since they induce core saturation, constraining their performance (as well as tripping various safety devices), and causes coils and cores to heat up. This heat can disable or destroy them, even inducing a chain reaction that can blow transformers throughout a system.
    This is precisely what happened on March 13, 1989: in Québec, as well as across parts of the northeastern U.S., the electrical supply was cut off to over 6 million people for 9 hours due to a huge geomagnetic storm. Some areas of Sweden were similarly affected.
    According to a study by MetaTech Corporation: if a storm with a strength comparative to that of 1859 were to strike today, up to 350 transformers would be broken and 130 million people would be left without power in the US. It could take 4 to 10 years and more than a trillion dollars to repair the damage.

    Solar Weather Forecasting

    By receiving geomagnetic storm alerts and warnings (e.g. by the Space Weather prediction Center; via Space Weather satellites such as SOHO or ACE), power companies can (and often do) minimize damage to power transmission equipment, by momentarily disconnecting transformers or by inducing temporary blackouts.
    ACE orbits the L1 libration point which is a point of Earth-Sun gravitational equilibrium about 1.5 million km from Earth and 148.5 million km from the Sun. From its location at L1, ACE has a prime view of the solar wind, interplanetary magnetic field and higher energy particles accelerated by the Sun, as well as particles accelerated in the heliosphere and the galactic regions beyond.
    ACE also provides near-real-time 24/7 continuous coverage of solar wind parameters and solar energetic particle intensities (space weather). When reporting space weather ACE provides an advance warning (about one hour) of geomagnetic storms that can overload power grids, disrupt communications on Earth, and present a hazard to astronauts.
    The spacecraft has enough propellant on board to maintain an orbit at L1 until ~2024.
    ACE provides about 15 to 45 minutes of heads-up to power plant operators if something’s coming in. They can shunt loads, or shut different parts of the grid. But to just shut the grid off and restart it is a $10 billion proposition, and there is lots of resistance to doing so. Many times these storms hit at the north pole, and don’t move south far enough to hit us. It’s a difficult call to make, and false alarms really piss people off.
    Long term preventative measures also exist to protect against Coronal Mass Ejections, including digging transmission cables into the soil, placing lightning rods on transmission wires, reducing the operating voltages of transformers, and using cables that are shorter than 10 kilometers. It might also be possible to develop and deploy large resistors that would add another level of protection to large transformers.

    You are correct bambam55. In fact, depending on the location of (any) vehicle, there is a chance that the disruption might cause some components of the car or truck to be effected, but still drivable. (Too many commas there). The truth is that scientists have tests in the lab that show how EMP affects electronics, but until we experience an E3 pulse, no one knows what to expect. From what I have read, there are way too many variables when you are dealing with an atmospheric E3 event. I am in the process of looking at doing just what you talked about. I have a 1984 AMC Eagle and am looking at either having replacement parts stored in a faraday or hooking up a points and condenser to the distributor. It will likely be storing replacement parts. I also own a 68 Mustang as a backup. Not good for the woods, but if I need to get somewhere on paved roads, it will work.

    I've always been told that non electronics such as real distributors and carburators would not be effected by an emp with alittle wrenching you can adapt these to most of the older style motors with electronic dist. set up, as far as the surviving comunities the only hope is that they armed and not afraid to shoot

Some of our SCADA architectures will protect data lines on the edges of a nuclear (Hight altitude) EMP (but don't quote me on this). The E2 component of the pulse is the easiest to protect against, and is kind of like the pulse produced by lightning. The E3 component of the pulse is a very slow pulse, and may last several minutes. This one can be caused by the nuclear detonation pushing earth's magnetic field out of the way or a Solar Event. The E3 is much like a geomagnetic storm caused by a very severe solar flare.
    Google the 1859 Carrington Event for more about an E3. NASA has a pretty good article about this event. Some scientists believe we are due for another one of these SUPER SOLAR events, within the next two years. Now the Carrington Event had little effect on the infrastructure of Europe and North America simply because we were in the early stages of technological development of the 19th century and the only real effects were telegraph lines being influenced. Because (most) modern electronics are not insulated against this type of event, the effects are speculated to be catastrophic. This has a subject of record back in 2005. The following is a quote from a House debate on EMP effects in the US.

    [Congressional Record: June 9, 2005 (House)]

    This likely consequence of a high-altitude nuclear burst was
    corroborated by Dr. Lowell Wood, who in a field hearing at the Johns
    Hopkins University applied physics laboratory, made the observation
    that a burst like this above our atmosphere creating this
    electromagnetic pulse would be like a giant continental time machine
    turning us back to the technology of 100 years ago. It is very obvious
    that the population of today in its distribution could not be supported
    by the technology of 100 years ago. And I asked Dr. Wood, I said, ``Dr.
    Wood, clearly the technology of 100 years ago could not support our
    present population in its distribution,'' and his unemotional response
    was, ``Yes, I know. The population will shrink until it can be
    supported by the technology.''
    Just a word, Mr. Speaker, about what this EMP is. It is very much
    like a really giant solar storm. All of us are familiar with solar
    storms and with the disruption to our communication systems. And this
    is like a really giant solar storm. It is kind of like really intense
    static electricity everywhere all at once, all over the whole country.
    It is sort of like a lightning strike that is not just isolated to one
    spot. Different than a lightning strike in terms of the intensities and
    so forth and the spectrum, but it would be everywhere all at once over
    a very large area.

    [Page H4340-H4345]

    The average Joe wanting to protect sensitive electronics has only one choice. Build a Faraday cage or Field expedient Faraday cage. The data I have suggests that putting your stuff under ground will not provide protection. The pulse will go into the earth deeper than you can dig. The only thing one can do is direct this energy around your device or devices. (Faraday)...
    Building one is not too difficult, grounding is also important. There are several valid sources out there for building your own Faraday. I have a working Faraday, but am looking into the possibility of using a microwave as a "reverse" faraday...

    Regarding vehicles. As far as I am concerned, any newer vehicle is subject to the effects of an EMP Event. This is proven by way of the new Law enforcement technology for disabling vehicles using small scale EMP generators. Unless you own a 1968 Mustang plan on some form of Bipedalism...

    Oh... I forgot.. Regarding Solar EMP Events: Data suggests they do not have an effect on humans. They will not cause "atmospheric" fires other than an aurora borealis as indicated in the Carrington Event.

    Regarding the above mentioned book "One Second After".... Excellent read on the societal effects of an EMP... Although I slightly disagree with the authors employment of the EMP event in the book, I do believe he hit the nail on the head on its after effects. I believe we are more likely to be hit with a Solar EMP than a Nuclear EMP.... SDI is alive an well... thank you Ronald Reagan
    And I'm off to renew my efforts/research on a faraday cage! THANK YOU for the extremely detailed information you have provided here!!! Hminus, THANKS!!!

    Everyone interested in this, you all should read the book by Dr. William Fortschen, it is called "One Second After". I have read it and am going to read it again and take notes this time. This book is based on DoD models, personal contacts and medical realities that accompany a long term (1 year +) disruptive event. He covers events that can trigger the event and how it is mitigated in a NC mountain community. Gangs are a major problem during this era, and pose a substantial security threat to a surviving community, that is just that-surviving. This can be anyone on this forum and all on this forum at the same time. Get it-read it...live.

    I hope I didn't overstate my last question about a 'burning sky' contingency. And I agree... I wouldn't want to be around after such a FUBAR event. I've just read a bunch (I know, don't believe everything I read) about the ongoing bunker excavations around the country for government or 'selected' use. If they're going underground, maybe we should make similar plans, or at least consider it. Just trying to arm with info. That's all.

    Thanks for the response.
