Fuck, I should have used an anti trump image to get 200 responses.

The simple answer is yes, the technology is there, why shouldn't someone use it at some point.

I don't really get this thread.

Some say that North Korea is going to launch an EMP off the west coast. I'm just wondering is that's a real possibilities or just a meme.

Emp is a thing yez

Yes. The starfish prime test in 1962 caused an emp that destroyed three satellites in low earth orbit and affected electronics 2500km away.

A high yield nuclear weapon detonated in the sky above the US would be devestating.

EMP is a reality because you can detonate a nuke in the atmosphere, leading to said electromagnetic pulse trashing all electronics below.

But: NK can't shoot a nuke as far as the US west coast. They can MAYBE reach the furthest point of Alaska, but even that is speculation.

pretty sure that's why their missiles have been blowing up in the air. they aren't failures... they're tests for atmospheric detonation. only one reason for that.

No thats the plot to the video game Homefront

>norks capable of EMP tech

Just lol

Chill, brosky, NK wont nuke US. Stop believing shill propoganda. Although EMP is possible, attack wont happen, at least not from NK.

>pic related

They can build nuclear weapons. And Nuclear weapons cause EMP.

So yes. Norks are capable of "EMP tech".

>detonate nuke above the country
>be more concerned you can't tweet or check your faceberg

jinkies

It doesn't just turn off twitter you dumb fuck. A strong magnetic pulse will cause metallic objects to heat up. It will also induce electrical current into any wire or circuit that isn't protected by a Faraday cage.

Electronic devices will literally be bursting into flames.

>Electronic devices will literally be bursting into flames
Don't you need electronic devices to host or visit twitter? you dumb cunt leaf, go fuck yourself

MFW I picked the wrong time to get a pacemaker and body piecings

Metal biscuit tins can be used as an improvised faraday cage.

Or metal screen. Just keep a roll of metal screen handy. And when the sirens go off wrap your beloved electronics in it.

Although the metal screen will get hot AF.

Although there's no point in throwing your phone inside a can because the insulators on every power pole are going to explode and it will take months if not years to restore the power grid. So there will be nothing broadcasting anything for your phone to receive for some time.

yes. that's why I print out pepes so when the power goes out I can still shitpost irl

Are you some 65 year old that got his cock pierced?

Yes we'll lose internet.
We'll also lose the powergrid, radar, airplanes, telecommunications...

Umm, yes.

Just keep solar and batteries in a faraday cage

Not going to happen unless its by North Korea or terrorists.

US shutting down would shut down China and Russia.

Of course there's always the possibility we'll EMP ourselves, ala 9/11.

I know that, it's non-disputable.
My issue with your post was that while you talked about the electronic interference, I think the biggest issue at the time would more likely be HOLY FUCK WE GOT NUKED.
Fair enough, electronics help you recover from some of those things but not for long.

Internet connected, PKI required John Deere tractors will kill more of us that we know.

Let me tell you a story son.
>City I live in issues "boil water" advisory. Carefully explains that a routine retest on a trap
sample showed traces of ecoli, but the circumstances under which the test came positive suggest that it's probably a lab error.
>go to store later that day to pick up a few odds and ends to make dinner with gf.
>Notice that every single bottle of water has been stripped off of store shelves. Like not just regular water, but over priced mineral water and shit too in a huge panic. People are so literally retarded, the mere thought of going the extra mile of boiling water before drinking it has spooked people into a giant frenzy that people bought up all the water from store shelves. People were on kijiji trying to sell water for a 1000% markup. Back to the store... I saw panicked mother, with children in tow, shopping cart had like 5 24 packs of 7-up in it. (Really? You're going to inject your children with liquid obesity because you can't be assed to throw a pot of water on the stove for 5 minutes?).

5 hours later. City confirms that the ecoli results were due to lab error. Water is safe everybody. Thank you for taking precaution.

That's how people act for a complete non emergency. 95% of Normies don't know what a faraday cage is. And the moment they realize Kikebook is gone they are going to be out in the streets turning over cars and setting everything on fire.

You stupid sheep fucker, the leaf was right in what he said and the way you phrased your comment implied that those things would be the worst that could happen. Typical moronic fuckin kiwi, how about you go fuck your flock.

Also let me tell you another story. Gather round.
>be me.
>Work at a company for over a decade.
>For the first 9 years I worked there, the door to the lunch room never latched properly. So whenever I leave the lunch room I just push on the door and it opens.
>9 years later lunch room door gets fixed.
>If I'm having a stressful day I push on the door and it doesn't open. Unconsciousmind is still stuck in those previous 9 years that the door didn't work properly.

Now think of all those shitskins being imported from war zones. Sure they are nice, and all smiles, and "hey how's it going N!dugu you coming to the company picnic this weekend?" Reformed by the stress free comfort of modern society.

When those lights go out, and we're practically living in the Congo, how do you think these people who spent 25 years raping and looting everything that moves, are going to have any chance in hell of holding onto their 5 years in western civilization?

My grand point being if shit goes south with the Norks or in Syria, It's going to take all of 24 hours for Normies to become your greatest foe. Prepare yourself to survive innawoods and arm yourself to whatever extent the law allows, because you're going to have to fight your way through panic stricken literal retards to get there.

>tfw you live in a faraday cage

t. radiofag

Honest question:

If an EMP is that devastating and could royally fubar everything...why is there even talk of a country nuking another nation instead of this?

Wouldn't the EMP cause more damage long term due to the total chaos and anarchy it would cause and the military presence that would be required for reconstruction of the power grid and restoring order?

Why do people believe another Hiroshima or Nagasaki will happen when there's more crippling technology now?

This could happen at any time via a large solar flare. God could certainly punish us this way.

It destroys all water purification systems and will lead to millions of deaths from disease all over the country

Starfish prime though only wiped out everything connected to the grid. Hard to say what will happen to other stuff. It did punch a hole in a generators insulation and fry the windings but it was a utility connected large generator. Wire is an antenna. A metal building goes a long way in protection. If you can't pick up an AM or FM station you have some good protection.

People know what a nuke can do, and are terrified of it. An EMP is the functional equivalent of rolling us back a a few hundred years, and the thought is that it's completely survivable. And it is, if you can stay away from the marauders.

>tfw only an EMP can save us from this website

Please best korea just DO IT DONT LET YOUR DREAMS BE DREAMS

Don't worry, our guns and cars will still work.

This is still on cloudflare, right? Owned by Google and on the google cloud, in/among one of 12 datacenters. Best Korea can't get 'em all.

>Sup Forums
>cockroach of the interwebs

Based leaf.
If you live in a city, your neighbor will probably try to kill you even before a nigger...

An EMP attack happens when a nuke explodes in the ionoshpere causing a huge amount of charged particles to move on a very short span of time. This causes an EMP pulse which will lose power with the square of the distance from the center of explosion. It would probably be easier to nuke directly vital points of a nation.
It depends on what the attacker wants to do after the attack (just annihilation? creating chaos? kill the population?)

dem quads, feels good mang!

>grabs axe
>gets in car

well anons I think its time we shut it down for good and move on with our lives, guess we gotta do it the hard way google

>your neighbor will probably try to kill you
not if you kill them first.

As far as I know the only official weapon that produces an EMP is a nuke. If a nuke goes off near your house not being able to browse Sup Forums because of the EMP will be the least of your issues.

>large scale EMP attacks
>when even your fucking smartphone has effective shielding

It's really just 2 different ways of using the same technology.

Military obviously has known about EMP for a while now. So any technology they can shield from it is by now shielded from it. But obviously you can't shield yourself from a nuclear fireball.

So a standard low altitude air burst would be employed if you were attacking a military target.

But if you wanted to create a massive amount of civil unrest over a much larger area, most of the civilian infrastructure isn't designed to be able to withstand an EMP.

In which case you'd take your nuke up to the ionosphere and detonate it there. Civilian infrastructure would collapse, and create chaos in the streets.

Hope so, I could use a break

But how will I shitpost?

Supposedly detonating it in the atmosphere is what does it, even if it's kinda far away and not harmful otherwise.

only if you get a 15 killstreak, at that point you might as well go for 25 and get a nuke

Isn't an EMP just a side-effect of a nuclear detonation in the atmosphere, or is MW2 lying to me?

No the whole EMP thing is cuz retards think modern warders 2 is realistic

It's true, but MW2 is full of shit in some areas, I imagine. Like how the EMP knocks out all electronics right down to the red dots on your gun, and then you get to the White House and it has power. I seriously doubt the White House has some anti-EMP barrier, which I doubt even exists unless maybe you're sealed in completely by metal.

E(lectro) M(agnetic) P(ulse)

you can create it w/o a nuke

>nuclear detonation
In theory you can create it but its pretty pointless since it will wipe out everything in the area.

faraday cages aren't enough to protect against the small wavelengths created by the EMP.
At some point, the cage will need to be so small that you might as well just encase your electronics in a block of metal, since it'll be the only thing good enough to handle the charge... though it might end up cooking your computer or whatever you store inside

Yes and no. you can't create an EMP as strong as a nuke's EMP without a nuke because the majority of energy released from a nuke is in the form of electromagnetic waves.

Toward the epicenter it heats up the air into a glowing sphere (or dome depending on altitude) which causes the gases in the air to expand rapidly, which causes the blast wave.

But the nuclear fireball itself is mostly an EMP. The pulse weakens by a factor of r^2 as you get away from the event center.

If you detonate it high enough though some of the EM waves will be reflected back towards the ground by the ionosphere. Hence the high altitude detonations.

Far more likely than a direct Nuke these days.

Good thing I keep secondary internet supplies in a leadbox! ENJOY NO Sup Forums FAGGOTS!

It's funny to think that people will still probably be shitposting on pol even if half of the world's countries fucking collapse

Are solar flares nuclear in nature? It's not like we can emulate them if they're not. But there must be so much potential to harness power from the unknown or maybe it's not possible to play god at all.

...

NK currently has two ICBMs capable of reaching most parts of the USA: KN-08 and KN-14. They are yet to demonstrate how well these work, but given their track record on previous missile tests, I'd say there's at least fifty-fifty chance they work just fine. Even if they work less than optimally, they have enough of them that very likely at least some of them would reach USA, and accuracy is not such a big issue with EMP attacks.

They also have satellites over the USA that might very well be capable of delivering small nukes for EMP purposes.

And as for the nukes themselves, they obviously have those. For EMP purposes small pure fission nukes are supposedly optimal (higher yield causes only slightly stronger EMP and H-bombs are bad because the first stage explosion ionizes atmosphere which causes it to absorb EMP's pretty effectively). And small pure fission nukes are probably what they have the most. They have apparently also managed to make small enough warheads to be deliverable by ICBMs (and possibly satellites).

EMPs are probably NK's biggest threat against USA right now. EMP on a major city will likely cause a total collapse of society there as almost everything depends on electricity and it will take a long long time to fix the whole electric grid. Obama betted everything on NK collapsing when old Kim died. He obviously lost that bet and now Trump is in a very difficult situation concerning NK.

tl;dr NK could probably wreck the electric grids of most major cities in western USA tonight if Kim so decided.

It would be extremely annoying

But there's no way it would take down the entire western banking system, you'd just have to drive out of range to withdraw cash again.

How fast do those things fly?

No way it would pass beyond California without getting intercepted

arent they detonated so high this does not apply?

Probably not very fast but it hardly matters. If you're doing an EMP attack you have to detonate the nuke hundreds of kilometers above atmosphere anyway. AFAIK you don't have any reliable ways to intercept missiles before they start their re-entry into atmosphere. Maybe you shouldn't have cancelled that Star Wars thing you had going in the 80's.

A decent ICBM goes about 7km/s at its fastest, so assuming it launched from the clisest point in North Korea to its furthest possible range it would take roughly 23 minutes to reach its target, either somewhere over Chicago or Florida depending on the best and worst guesses of the unknown capability of NK missile tech.

There are only two systems in the world capable of intercepting ICBMs. You yanks have one of them, and it means the National Missile Defense base in Alaska would provide your best chance of intercepting a missile launched from Korea.

Normally you detonate nukes in the atmosphere. If you want to do an EMP attack you specifically don't detonate them in the atmosphere but a few hundred kilometers above it. Both ways you get an EMP, but atmosphere absorbs EMP waves so the pulse will only travel a few dozens of kilometers in atmosphere. If you detonate it hundreds of kilometers above atmosphere the waves will come from the above, meaning they only have to travel through 10km or so of thick air, even if you're far away from the epicenter. That way you can destroy electric grids in more than a 1000km radius.

>Starfish prime though only wiped out everything connected to the grid. Hard to say what will happen to other stuff.
If it has anything that can act as an antenna it will get a power surge, whether that power surge is strong enough to destroy the device depends, but nowadays most electronic devices get fried quite easily. Starfish prime also wasn't meant for testing EMP effects, they used thermonuclear warhead which are really quite bad for EMP purposes. (for reasons i described in ) Still it did some damage to electric grid in Hawaii which was 1500km away. Back then electric grids were also much more rugged and could survive stronger power surges than the ones we have nowadays.

>They also have satellites over the USA that might very well be capable of delivering small nukes for EMP purposes.

utter nonsense.

Well Kwangmyongsong-4 at least is on orbit that goes over USA. And if you have miniaturized a warhead to fit into an ICBM, you're not too far away from fitting one into a satellite.

Oh, and it also happens to be on perfect altitude for EMP detonation. Still, it's very unlikely that it actually carries a nuke, but definitely not impossible. And it's very possible that they might launch a satellite carrying a nuke in the near future.

any source on that satellite?
