Default Do EMP's Pentrate far into ground earth?



Advertise Here

My idea was to get a couple of cheap flash drives and without having any form of Faraday cage protection, would it be possible to drill/dig far into the ground? (i'm thinking anywhere from 20+ feet?..) --and have your data protected from (lets say a ) "powerful solar" EMP??

(i would like to do it in multiple marked locations)

Would being far enough into ground earth discharge any EMP significantly enough that you wouldn't need any faraway cage covering?

,THANKYOU for any and all responses

Ok, after the mega EMP blast kills, burns or destroys every electronic it can reach how do you plan on reading these flash drives you saved?

in the late 1800's the us had telegraph systems brought to a halt throughout the country because of a massive CME (Corona Mass Ejection) a natural emp. The telegraphs were powered by land batteries ( look it up/google it, makes for very interesting reading) any way... it took several months to repair, replace existing systems including the earth batteries...
a faraday cage above ground should be sufficient....

well,, the question applies to computer electronics as well. if you can bury a drive then also a pc? right

well if my logic is correct..

Thanks for that suggestion. definitely will check it out, does sound interesting.
all i want to do for now is just make double sure my files are safe,
a computer and couple flash drives would be nice to have secure
It would be Nice to have a PLAN A And a PLAN B

A particularly scary thing about EMPs -- especially man-made ones -- is that a smart foe could easily get your protected stuff as well unless you had multiple backups. Wait a few days after the first strike to allow folks to get all their backup EMP-protected stuff out, then hit 'em again.

I consider an EMP strike highly unlikely, but hugely destructive if it would occur -- natural or otherwise. Scary stuff.

I might as well also look for a cave nearby and some mountaintop locations
that i can store my flash drives. Might be some 'safe spots" to try. And yes i will have them water proof.

I AM NO EXPERT but in my research, I read that the EMP will follow all wires hooked to the grid. Also that some devices unhooked can pick up the voltage spike. Especially object with internal and external antennas and even object with cord(essentially an antenna). And what do we use nowadays without a cord?

In an underground shelter, it is recommended to leave all devices you want protected either:
1: unplugged with antennas disconnected, and hooked to an external ground system that hooks to an 8 foot Copper pole that goes through the bunker floor. Or

2: in a Faraday cage. This should also be connected to above ground setup.

I know this isn't the answer you are looking for but maybe it will offer some insight.

I would like to add that I like your idea of storing info electronically as long as you take every precaution to protect the computer you intend to read it on. And have a reliable source of power such as solar.

You can store every bit of information you will ever need on an external hard drive or multiple flash drives and just access as needed. Even off the grid. Once it is saved, you will no longer need the internet.

But personally, I still would keep paper copies of as much as you can. I have tons of informational books to fall back on.

Yeah paper over everything.
A good fallout shelter should provide enough to protect against EMP. At least that's what all the commercial shelter builders say. As long as it isn't connected to mains power or other long cables (anntenas for example). But if you're paying that kind of money to build a shelter, I'd also use a faraday cage, just to be sure.

Shallow underground burial does not provide significant protection; and deep burial (10 feet or more) is not worth the construction effort.

As said, this is for commercial fallout shelters. But it's an interesting read nontheless

I think copper flashing will protect them

Have you purchased or created a cage yet? Curious how easy it was.

thanks for the info, paper is nice though until it catches fire

Avoid the single-event fallacy. In assessments of potential tactical situations, don't assume that EMP will occur once and then be over. The contrary may be the case. An aggressor may initiate a precursor attack with high altitude EMP to initially damage unprotected equipment, and then follow-up with additional high altitude or surface-burst explosions to exploit the tactical situation. The only valid countermeasure is to adopt and sustain EMP mitigation postures consistent with tactical missions.

Talking

I'm confused

You are thinking about digging 20-feet deep to protect a couple of flash drives?

Caves?
Fallout Shelters?

EMP is completely, 100% shielded by a -


There's room in there for a whole stack of laptops and about 10,000 flash drives

Don't go overboard people

Don't go overboard people
i was actually planing on digging a hole and using those cans
trust me id rather not play games with all the work put into my digital files
id rather be 100 percent safe then 10 percent too late
how do u know that works 100 percent for emps? if it does then why dont people use that over farday cages/
also, could it be possible that there ar emps of varying magnitude, so if there was a super emp it could fry whats in the can?

Since we have never personally experienced one, we can only speculate. But all the experts say regardless of the EMP strength, as long as it's not touching the metal itself when it strikes you'll be alright. It's about the same principle as lightning hitting and the faraday cage serving as the ground rod from what I understand. What do you have on them Flash Drives that is so important??? Home Porn????
