Or load on ammunition, and be ready for your neighbor to go cannibalistic within 3 months...
Days. After the soviet union fell in Armenia there was no supply of food the first days. Also no gasoline nothing. The first day people were normal. Second day people started stealing. Third day all birds and rats were shot for food. Luckely soon food became a normal thing again. But chaos is quickly there. I believe even quicker in rich western countries. Most men and women cant survive on their own for a week.
Tangentially, that's a reason not to use any "cleaning" additives in your toilet water tank, since you are rendering some emergency water undrinkable.

#223Is there any danger of people flying in planes during this time? Will there be any radiation exposure?
It's a magnetic field, no? Is there any particular radioactive component? I'd be more worried about the acute effect on the plane's electronics, the whole point is they disrupt electrical systems.
Charged particles moving fast are ionizing radiation too. I wouldn't expect a ton to get through atmo though.

#224Implications! - Power systems: Possible widespread voltage control problems and some protective systems will mistakenly trip out key assets from the grid. - Spacecraft operations: May experience surface charging and tracking problems, corrections may be needed for orientation problems. - Other systems: Induced pipeline currents affect preventive measures, HF radio propagation sporadic, satellite navigation degraded f…
Uuuuh I have a flight today 8pm CT . What will this mean for airplanes?
Is it a Boeing?

> Okay, that's averaged over 15 minute time slots, but even the connection for my house is only rated 13.8 kW! In the US we have single-phase (split-phase) 120/240v 200A service drops for houses, 48kW. Houses over 3,000 square feet with electric heating, electric ovens, electric water heaters, and electric air conditioning can push 150A peak demand, and a 200A service drop is not much more expensive for the utility t…
Not needing a sub-panel is almost certainly the reason. The North American residential electrical code limits how many circuits you can put onto a generator based on the circuit capacity, not the expected use. You aren't allowed to pinky swear that you won't run your electric oven and dry laundry at the same time. It doesn't matter that your generator will just trip its breaker or die. So if you want to have most of…
Alternatively, you put in load shed devices. They're basically fancy self-resetting circuit breakers that trip when the generator begins to be under too much load. They all trip at the same time and then come back up in a pre-determined sequence.

Humanity is good in sweeping problems under the rug and not preparing to various threats.

If you really want to be safe: put it in a cardboard box, wrap the cardboard box in air tight aluminum foil or a metal container, and then put the whole thing in another cardboard box to prevent any grounds or shorts.
That seems pretty excessive, IIRC if there's not a really long linear length of wire involved (e.g. power lines) then things are probably fine.
This would better prepare them for an Air Burst

we got the smaller 42 gallon one, and.. with two people and a pet... it might last a couple weeks tops, I'd think, if we rationed (~2-3 gallons per day?)
I don't think I've ever drunk two gallons in a day in my whole life. Sedentary survival needs in reasonable climates are maybe a third of that.
Go hiking in 35 degree weather on Mallorca, you'll easily exceed that.
But that's not really disaster-relevant, no.

#230PJM (the US east coast power grid) has issued a warning: 104202 Warning Geomagnetic Disturbance Warning 05.10.2024 13:48 PJM-RTO A Geomagnetic Disturbance Warning has been issued for 13:48 on 05.10.2024 through 21:00 on 05.10.2024. A GMD warning of K8 or greater is in effect for this period. Times are US EDT. This is a warning only. No actions are listed yet.

This chart of the real-time K-index is pretty interesting: https://www.swpc.noaa.gov/products/planetary-k-index#:~:text....
I found this after looking up what "A GMD warning of K7 or greater" means.
