An Exercise To Model a "Solar Radiation Katrina"

Hugh Pickens writes in with an update on the warnings we discussed a year back about the dangers of a "solar Katrina." Now NPR is reporting on a tabletop exercise mounted in Boulder, Colorado by government workers attempting to model the effects of a worst-case solar electromagnetic storm. "...an exercise held in Boulder, Colorado, has investigated what might happen if the Earth were struck by a solar storm as intense as the huge storms that occurred in 1921 and 1859 — a sort of solar Katrina — and researchers found that the impact is likely to be far worse than in previous solar storms because of our growing dependence on satellites and other electronic devices that are vulnerable to electromagnetic radiation. 'In many ways, the impact of a major solar storm resembles that of a hurricane or an earthquake,' says FEMA Administrator Craig Fugate, except that a solar Katrina would cause damage in a much larger area — power could be knocked out almost simultaneously in countries from Sweden to Canada and the US. In the exercise, the first sign of trouble came when radiation began disrupting radio signals and GPS devices, says Tom Bogdan, who directs the Space Weather Prediction Center. Ten or 20 minutes later electrically charged particles 'basically took out' most of the commercial satellites that transmit telephone conversations, TV shows, and huge amounts of data we depend on in our daily lives. But the worst damage came nearly a day later, when the solar storm began to induce electrical currents in high voltage power lines strong enough to destroy transformers around the globe, leaving millions of people in northern latitudes without power."

    You're mixing up two effects. You're correct that the direct EM radiation would affect largely only the sunlit portion of the Earth. However, the "second punch" of these events is the large burst of protons that arrives the next day -- it's the solar wind, but several orders of magnitude larger than usual.

    These protons are affected by the geomagnetic field, and (to simplify a lot) rain down in large regions generally centered around the magnetic poles (cf. the auroral ovals), where they induce very large currents in long conductors like power lines, leading to general power failures that could not be easily repaired.

    This wouldn't be your garden-variety blackout -- it would require physical replacement of massive equipment for which there are no spares readily available -- at least not in the quantities needed. Large numbers of people -- entire provinces and states in North America, and likely entire nations in northern Europe -- would be without power for months while new equipment was manufactured and installed. This would lead to mass migrations out of these areas, which would lead to social disruption and significant loss of life as critical systems, whose backup generators and other emergency systems were not designed for such an extended outage, failed.

    I was in south Florida for Hurricane Wilma, and I can report to you that the social structure of the region almost broke down during the week or two the region was without electricity -- and this was a natural disaster, albeit a severe one, that people understood and had largely prepared for. Power was restored relatively quickly then, because (a) the causes, downed power lines, were easy to find and repair, and (b) there was a massive influx of utility workers from the rest of the country to help out.

    Although this doesn't affect your main point, it's worth mentioning that a lot of the folks who got no or a minimal insurance payment were insured against flood damage, but the insurance companies found creative ways not to pay. An example of the kind of thinking that was employed: your neighbor's house crashing through your living room isn't water damage, so we don't have to pay the flood policy on that damage. But because the incident in question was caused by a flood rather than a fire or tornado, we also don't have to pay the regular homeowner's policy. Therefore, you get only payment for cleaning up the water damage. Another common tactic was to refuse to pay unless the homeowner could provide documentation for their policy, which was of course lost in the flood.

    From what I read this radiation, magnetic as well as assorted stuff from Gamma to long wave radio spreads out uniformly and is spread over a large area by the time it hits Earth's orbit.
    The large lump of particles is far smaller and might miss the earth, pass close by or whack us. If it whacks us, we get these large induced currents in long lines and the peak volts associated with them, so with a solar flare known to be in transit we need to snoop it to see where the ejected material is going to hit and when. With this knowledge we can close down some transmission lines and produce a man made blackout of short duration that we can end in a controlled manner, with little or no destruction of lines and transformers. Once the flare has passed, back to the way we were. As for satellites? Possibly they can be powered down or placed into a mode that minimizes the flare damage, and then turned on afterwards, and we will suffer less destruction, but we will have the interruption of services as a lesser evil.

    On September 2nd, 1859, the Earth went mad. Auroras lit up the sky over Australia, Japan, Colorado, and even as close to the equator as Venezuela. The worldwide telegraph system, which had gone from a laboratory curiosity to the wonder of the age in the previous twenty years, went haywire--sparking operators, scorching paper tapes, and mysteriously still transmitting messages between Boston, Massachusetts and Portland, Maine although the batteries that ran the system had been disconnected out of self-defense. At Kew Gardens in London, a set of magnetometers designed to study the Earth's magnetic field started showing "disturbances of unusual violence and very wide extent" on August 27th; by September 2nd they were literally off the charts. No-one knew what was going on, with one possible exception. ...

    So equipped, Carrington was in a good position to catch an odd sight on September 1st, 1859 at 11:18 in the morning (if that seems peculiarly exact, bear in mind that the likeliest people to have precise chronometers at the time were ship's masters and astronomers). He was engaged in his usual observation schedule, projecting the Sun onto a large darkened piece of glass and measuring sunspot positions. In particular he'd been interested in an enormous sunspot cluster north of the solar equator which had appeared on August 26th. It was large enough to be of interest to astronomers world-wide, so there is at least one photograph of it--if you're trying to match it up with the chart above, remember that images in reflecting telescopes are inverted top to bottom.

    He happened to be looking at the cluster when four bright points of light suddenly appeared from within it. He took a moment to check that the full strength of the Sun hadn't somehow managed to come through some hole in his equipment then, satisfied that it was actually happening on the solar surface itself, called for someone to come confirm what he was seeing. As Carrington himself put it, then "on returning within 60 seconds, [he] was mortified to find that it was already much changed and enfeebled". It disappeared entirely within a few minutes.

    I lived in a suburb of Detroit during the rolling blackout in the northeast. Drives that would normally take 10 minutes took hours, there were lines at the gas stations, people who didn't have cash on hand were scrambling to borrow money because they couldn't get money from the ATM, etc.

    If you live in a colder climate, it might be better to just buy the generator. Burning those stock certificates will only keep you warm for a short while.

    Why does any disaster have to be Katrina, especially when there is no comparison to the scope or nature of Katrina.

    Because they are comparing the effects, not the scope or nature. Katrina caused a lack of food and water for an urban population. The cause will be different, but the same lack will be present.

    I find the dialogue to be western centric and kind of out of touch

    It's a study by the American government on the effects of a geomagnetic storm hitting the United States on the American electric grid. How would do you expect it NOT to be American-centric? America doesn't run the electric grid in your country, and your electric grid is probably different from ours. If you want relevant data for your grid, you'll need to do it with relevant local data. Have your government ask for a copy of this study. I'm sure the Americans will gladly offer it up if your country is friendly and asks nicely. Then your country can use it as the basis for your own analysis and study. Then it can be as [insert your country name here]-centric as you need it to be.

    Honestly, the challenges are going to be different, so the study has to be done bearing in mind the specific geographic challenges.

    Oh noes! My data is not available to me!!

    Electricity will be gone, which means for a significant portion of the population of America potable water will be gone. Large cities everywhere are utterly dependent on electricity for basic services due to extreme population density, and in some cities the body count clock starts ticking within a few days of power loss. The higher the population density, the more interdependent people are.

    What about places where lack of electricity is all it takes to cripple a water purification system or a hospital?

    As in New York City? Boston? Los Angeles?

    Honestly, this study is relatively useless outside America and maybe Europe. And some areas in Europe might have even been smart and put circuit breakers in their transformers. America sure as hell didn't, and that means our entire mains grid is now at risk due to geomagnetic interference. Those transformers have to be replaced one by one, and there is one of them for each and every house in my area. Plus there are some HUGE ones at power substations that supply entire towns. The power company keeps a supply of all their various types of transformers them because they do burn out and go BOOM, but they might have 5-10% of what they'd need if every one of them toasts out across the entire grid. It'll take time to make the rest.

    Subsaharan Africa doesn't have as sophisticated a power grid, power tends to be generated more locally, so a water purification system in Africa is probably not going to suffer from any ill effect due to the collapse of a power grid. Not to mention most rural areas haven't built up the dependence on electricity. Their response will be markedly different than, say, New York City, or Boston. Especially in the winter when people will freeze to death in a few days if they aren't prepared. You can't leave the high-rise and start a fire, and if you can the other 4,999,999 people around you will all have the same need, and you'll run out of fuel in a couple of days, even if you treat the library and Central Park as fuel sources.
