EMP, The Electromagnetic Pulse

Probably better off staying in AK. The winter will eliminate most of your unprepared.

 

I worry that it will also eliminate me! I'm good for about 90 days in the summer time (following my FIL viewpoint)

In the winter, it's two weeks and if it looks long term - sell what we can and bail....I have monitor heater, but it requires AC to work....and fuel.

No AC, no fuel. No fuel, no heat. No heat... pretty circular.

 

A peer reviewed paper just released from China of all places.

Why am I postirig this one?

From the Abstract summary:
Abstract
The reactive power losses caused by the power grid Geomagnetically Induced Current (GIC) severely disturb the static voltage stability of power systems, and may even trigger voltage collapses. In this paper, the 1 V/km uniform induced geoelectric field is adopted to analyze how greatly geomagnetic disturbance (GMD) can influence the static voltage stability of power systems, given the features of GMD disasters hitting the power grids of China.

China's electric grid suffers from many issues - mostly from poor engineering and substandard materials.. The North American grid,, from decades of neglect and running at capacity with little in the way of redundant paths..

The Chinese data and findings parallel several of the papers I posted earlier on the board re:GIC issues. This paper was released this month.

Nothing has improved in the outlook for GIC caused outages, particularity in the northern tier of the US.

This back ground information presented for your review and any action as you may find provident.

 

okay, there were many forums to choose from but this was the last one I read so I will ask the questions here.
I am way out of my league here so dont laugh too hard at my questions!
so no matter what causes the EMP, i.e. solar flare or man made device... it takes "X" amount of grounding to overcome that surge?
A faraday cage also needs grounded?
I happen to have access to an almost unlimited supply of copper and galvanized ground rods and grounding accessories. would it be feasible to have ground rods driven in my yard next to the drive way and some how ground my truck if we see a solar flare coming or if the air raid sirens go off? Jumper cable from battery to ground rod? or would an earth ground just drain the truck battery?
id like to find a use for all these supplies.

 

A solar storm isn't going to effect any not connected to the power grid. Anything smaller than an off grid solar farm shouldn't be effected by a solar storm.
It is very difficult to produce an emp out side of a vehicle without a nuclear weapon strong enough to damage it.
It took something like thousands of volts per kilometer of wire of induction to even start to effect vehicles that were running. I think the test I read was 50,000v per km of wire. That appears to be impossible to get from solar. It takes a direct lightning strike on a turned off vehicle to damage it.

 

So the EMP that took out the warship and the cruse ship had to be massive.

 

that brings up another point. A lot of what I am reading sounds like the things that are large enough to cause problems will have either a Primary or secondary "damaging effect" that would render the efforts to protect the item useless. I may be wrong… I like to be prepared but can we be truly ready for EMP? I don’t mean as a society… I hear (and my nomenclature is probably wrong) people talk about “hardening the grid” and things like that. I’m sure that is important… however, say I wanted to protect a HAM radio setup… given an EMP strong enough to ruin those types of electronics, how would I protect my set up? I’m sure it all varies greatly and I’m speaking in broad general strokes. Perhaps I’m just to green on the issue.

 

what one is more likely to disrupt communication and what one would be more "grid" centric? solar flare sounds more like a grid if I’m thinking literally about long runs of wire... but does that mean that small electronics would survive if they are simply unplugged?

 

Yer Tax Dollars at work - the EMP Commission reports belong in all EMP threads. An EMP won't likely affect your vehicle, but the power grid and communications would suffer. With a CME, however, all bets are off.

Solar flare and nuclear will disrupt communication in their own ways.
Both will energize the upper atmosphere and scramble signals from satellites and communication from the ground that bounces off the ionosphere for hours even days with solar.
Solar flares are more likely to take out geosynchronous communication satellites by various mechanisms because they are 100,000 miles up, it may fry them on the spot or they may fail days or months later.

You better be able to unplug your whole house from the grid.

 

A note about grounding,
Several years ago I met a fellow that worked for the local phone company, and in order to establish a round for the local service they had to first build a underground vault and drive copper plated steel rods in every direction from that vault to establish enough ground to satisfy the requirements because there was too much quartz in the area.
Another fellow I met watched lightening hit a yard next door and travel past the chain link fence and into his own ground and into the house and it burnt up his electronics.
A man I knew well installed the microwave towers in the mountains and for His own radio antenna ran a ground from the antenna tower to the grounding rods around the antenna in a long sweeping arc to hold the flow going to the grounds.

 

The only real ground I have around here is my 120 foot deep well.

 

I found this worth the time to watch

 

Yes I also have access to ufer grounding accesories or bonding bridges. It seems most new houses are using those to ground to their foundations around here. Can you "Over" ground a system? Again please excuse my lack of knowledge on this subject.

 

I have simple steel cabinets for my electronics . I figure that if these don't survive I probably wont survive either.

 

Severe thunderstorms hit parts of Queensland, Australia on October 18 and 19, 2021, bringing heavy rain, giant hailstones, and tornadoes. The largest hail was reported in Bloomsbury and Yalboroo, north of Mackay in North Queensland on October 19.

The Australian Bureau of Meteorology forecaster Shane Kennedy said they've seen some convincing images of hail up against a tape measure of 16 cm (6.29 inches).

The Australian record is around 14 cm (5.5 inches) mark, Kennedy said, adding that it looks like they have a new Australian record for hail.1

Hail that size has a terminal velocity of well over 100 km\h (62 mph).

The world record for the largest hail is 23.59 cm (9.29 inches) recorded in 2018 in the town of Villa Carlos Paz, Argentina.
(Giant hailstones pummel Queensland, likely the largest seen in Australia since records began)

South pole keeps wandering....
