wfb north korea first time week reveal plan use nuclear arm space-based electronics-disrupting emp attack addition direct warhead grind blasts.the official communist party newspaper rodong sinmun publish report monday emp might nuclear weapons outline electromagnetic pulse emp attack produce detonate nuclear warhead space general strong electromagnetic pulse generate nuclear bomb explosions 30 kilometers 100 kilometers 18.6 miles 62 miles grind severely impair electronic devices electric machine electromagnetic grids destroy electric cable safety devices say article author kim songwon dean kim chaek university technology pyongyang discovery electromagnetic pulse source high yield high-altitude nuclear explosion test process give recognition important strike method stated.the official discussion north korea plan conduct emp strike likely fuel debate threat former cia director jam woolsey say north korea capable orbit emp nuclear weapon satellite.some liberal arm control advocate dismiss emp threat pyongyang far-fetched arm control advocate jeffrey lewis april dismiss threat emp attack laugh reporter question favorite nightmare scenario small group dedicate people tell npr.disclosure north korea intention use nuclear force emp attack come u.s. intelligence agencies continue analyze late underground nuclear test north korea sept. regime say first hydrogen bomb explosion.senior administration officials say initial assessments nuclear blast northeastern north korea indicate large test detonation far much large underground test carry last year regime sixth nuclear test.u.s nuclear technicians make definitive conclusion specifics device specialists try determine test involve hydrogen bomb pyongyang assert device design emp attack also assess whether test use boost fission technology.hydrogen bomb advance devices use two-stage explosion process produce massive explosion boost fission devices less sophisticate technologically require nuclear fuel highly confident test advance nuclear device see far inconsistent north korea claim u.s. intelligence official said.however final conclusion type yield blast expect several days data test analyze nuclear weapons experts los alamos national laboratory new mexico.also large explosion perhaps 100 kilotons equivalent 100 tons tn likely produce significant vent radioactive particles air.special u.s. intelligence aircraft include wc-135 nuclear sniffer jet conduct flight near test zone gather sample particles test.experts say emp attack korea real dark possibilityaccording business insider experts believe realistic threat point time emp attack make happen north korea launch low-yield nuclear missile submarine ship even balloon explode high altitude atmosphere.the potential result blackout eastern grid supply 75 power unite states.if emp attack take place would beyond anything see commission assess threat unite state electromagnetic pulse attack establish congress 2001 estimate within 12 months follow nationwide blackout 90 us population could perish starvation disease societal breakdown electronic armageddonin practical term catastrophic blackout would bad cities would instantly deprive population access drink water refrigeration heat air condition telecommunication food store would loot within matter days gas station would cease function without electricity.without internet access power commerce advance methods communication would stop would tv radio phone credit card transactions cash withdrawals bank would impossible paper money would become worthless bitcoin would cease exist along stock market.newt gingrich speak senate committee energy natural resources early month say emp attack would send us back 18th century problem outside help arrive within days chaos begin reign civilization rather thin veneer humans acquire centuries mask cover hard-wired survival instincts mask slip could mean end world know it.we ill-prepared emp attackus politicians major utilities kick road come emp preparation edison electric estimate shield transformers us grid system could cost 20 billion.granted american power company study ways protect electronic grids attack tangible result slow coming.the current option emp attack would replace damage destroy transformers however say scott aaronson manage director cyber infrastructure security edison electric replacements transformers must procure foreign suppliers could take 18 months.peter vincent pry leader task force national homeland security believe north korea close launch emp attack many analysts believe want congress work hard cut red tape allow innovation necessary mitigate threat.in pry opinion emp attack would ultimately kill americans direct nuclear blast could book long sunday describe several plausible emp attack scenarios.pry think first nation use nuclear weapons today even rogue state like north korea iran immediately become fear credible nuclear power world formidable force reckon perhaps dominant actor new world order sensible way prepare emp attack maybe stock food water fuel batteries emergencies always good idea well own stash gold coin hard assets.while eat gold preppers say kind money prevail millennia kim north korean technical university dean state high-altitude explosions conduct stratosphere space blast wave limit lack air thinness air explosions occur altitudes large amount electrons release result ionization reactions high-energy instant gamma ray radioactive ray say electrons form strong electromagnetic pulse emp interaction geomagnetic field detonation would create strong electric field 100,000 volts per meter approach grind destroy communications facilities electricity grids report said.the emp report publish monday day state-run outlet report visit north korean leader kim jong un nuclear weapons facility also mention plan use nuclear weapons emp attack hydrogen bomb whose power nuclear bomb adjust tens kilotons hundreds kilotons accord target strike multifunctional thermonuclear warhead enormous lethality destructibility also even carry super-powerful emp attack expansive area detonation high altitudes accord strategic goals report say korea reveal plan unleash unimaginable attack could lead electronic armageddon
