Can North Korean Hydrogen Bomb Evaporate New York in Case of Surface Blast?
How much damage can it cause
Professor of Korean studies at Kookmin University, Seoul, told Al Jazeera that it can completely destroy New York. “Such a device could evaporate the entire city of New York completely – no one would stay alive. With an atomic bomb, you can kill half of Manhattan, at most,” he said. Website Nuclear Secrecy, assesses the damage on New York in case of a blast yielding 50 kilotonnes. Its findings are disturbing.
Effects radii for 50 kiloton surface burst (smallest to largest): Fireball radius: 380 m (0.45 km²) Maximum size of the nuclear fireball; relevance to lived effects depends on height of detonation.
If it touches the ground, the amount of radioactive fallout is significantly increased. Air blast radius (20 psi): 0.8 km (2.02 km²) At 20 psi overpressure, heavily built concrete buildings are severely damaged or demolished; fatalities approach 100%.
Radiation radius (500 rem): 1.64 km (8.41 km²) 500 rem radiation dose; without medical treatment, there can be expected between 50% and 90% mortality from acute effects alone. Dying takes between several hours and several weeks.
Air blast radius (5 psi): 1.69 km (8.94 km²) At 5 psi overpressure, most residential buildings collapse, injuries are universal, fatalities are widespread. Thermal radiation radius (3rd degree burns): 2.87 km (25.9 km²) Third degree burns extend throughout the layers of skin, and are often painless because they destroy the pain nerves. They can cause severe scarring or disablement, and can require amputation. 100% probability for 3rd degree burns at this yield is 9.5 cal/cm2.
If NK nuked NY, I'm sure we'd elect a Korean
Kimmy will try going long, to the degree of nuking Yellowstone, nuking Fukushima, Honolulu or indeed a high altitude emp burst which is the most difficult.
Thing is they cannot shield a device strong enough.
But if they blew up Fukushima the fallout would indeed nearly destroy America.
Nah, a small dirty bomb at the most.
The NORK blast sounds like boosted.
People will never learn. Americans seem to be the worst.
IMHO, the problem was Bush — he allowed his political enemies to set the tone and make false accusations. This enabled Obama to win. I do not like Bush for this reason.
Freedom! The benefits are so obvious by looking at Korea.
If little fatso cared a smidgen about his people he would take his fist off them.
My husband has a lot of stories about Korea..none of them good. They expected something like an 85% casualty rate if things exploded with N.Korea - so they were sitting ducks.
If the Chinese are funneling their designs to the Norks, as seems to be the case, they favor 5 Megaton city busters.
For comparison, the US mostly deploys half megaton warheads.
How about taking a shot at Cheyenne Mountain (NORAD)?
CA....
I continue to be amazed that no one is talking about the devastation from an EMP attack, the easiest to do, and one for which the Nork weapons are capable. Properly placed, one of their dinky little devices could take out (irreplaceably) the North American power grid and a large fraction of electronic devices across the US. Read the book ‘One Second After’ (Newt Gingrich forward). Why the President has not explained this to the public .... well, I think they are withholding this for the last discussion ... just before the balloon goes up.
Fusion devices are opened ended on maximum yield. The important thing is weight. Perhaps this weapon is at the max deliverable weight for their missiles.
EMP is a line-of-sight weapon when detonated in space. 1MT 400 miles over Kansas takes out the North American power grid coast to coast. Period. Lower yield weapons are more effective than very high yield weapons. That 50MT weapon was not detonated in space. Russkies like their electricity.
When Czar Bomba was tested, the Soviets didn’t have the capability of putting anything that big into space. They had a hard enough time just dropping it from a specially modified tupolev bomber and getting away in time.
How about some target practice...missile or bomber
39.040277 deg North
125.739722 deg East
USS Pueblo, Potong River NK
Captured Jan 23, 1968
that book 1 second after that seems to be the primary source for everyone’s emp worries is completely absurd and exaggerated and was basically written for some lobbyists to secure a lot of grant money for certain clients
There are two and possibly 5 countries with the wherewithal do successfully pull off a hemp detonation IF it was not intercepted in route—one or a few missiles head this way you can bet that there will be enough countermeasures to stop or at least limit the damage...the norks are far from able to pull this off anytime soon
Also, emp effects are based on long circuits pushing up enough energy to fry stuff....power grid is vulnerable but most vehicles, even modern, would be largely unnaffected, as would generators and other electronics that are not plugged in
I know from personal experience parts of out power grid are protected with basically giant fuses and much of it would be brought back online fairly quickly
If you want something credible to worry about then worry about the c&c systems of the power grid, banking ssytem, and toher critical infrastructure being hacked...there is stuff there that should keep you from sleeping well
A hemp detonation. Awesome. Maybe the little fat guy will chill out.
It’s the transformers. They are not protected for the most part and already pretty much built on demand, not stockpiled.
There was a study during the cold war that looked at the idea of high altitude detonations to fry the incoming russian nukes just before turnover during midcourse flight. The neat thing about using nukes as interceptors is that close is ok and the emp fries the missiles guidance system.
Mid pacific for NKorea missiles doesn’t even harm the US. The Nike Hercules even had nukes for terminal defence. Better your nuke exploding at 100,000 ft plus than their nuke going off over your city at 2500 ft.
Lofting one or two nukes is a no win for N Korea, which is why we can’t let the pudgy boy king build 50 or 100 missiles and warheads.
They actually deployed a nuclear missile as part of a 50s / 60s era system for bomber defense.
I think the biggest probability is a boosted device and the item in the photo the Norks released a couple days ago was put together using pictures found on the Internet just for scare purposes. There is a chance that they actually got all the proper components and the technology from someone else.
On the same line of thinking, did they get a guidance system that can actually put the device where they want it. even then they have shown the reliability of their missile airframes is not the best.
