Last weekend, North Korea conducted their most powerful
nuclear test ever, with what was believed to be a hydrogen bomb in the northern
part of their country. The explosion was so massive that it triggered a
man-made earthquake measuring 6.3 on the Richter scale. If North Korean sources
are to be believed, the bomb tested was a powerful 100 kiloton weapon.
But that’s not all. To take the massive threat to an
entirely different level, the North Korean state news also warned that a
powerful hydrogen bomb could be detonated at a high altitude to create an
electromagnetic pulse (EMP) capable of taking out parts of the American power
grid. (PS: They have two satellites orbiting over the United States that could
potentially carry out such an attack.)
Knowledge is power, so let’s break down this information
with some explanations.
What is a hydrogen bomb?
A hydrogen bomb has some similarities to an atom bomb,
but works using an opposite chemical reaction and is far more powerful. Both
hydrogen bombs and atomic bombs are nuclear in nature, so after the initial
blast, there would be deadly radioactive fallout and environmental issues.
An atom bomb is what was used by the United States
against the Hiroshima and Nagasaki, Japan during World War 2.
Nuclear fission produces the atomic bomb, a weapon of mass destruction that uses power released by the splitting
of atomic nuclei.
When a single free neutron strikes the nucleus of an atom of radioactive
material like uranium or plutonium, it knocks two or three more neutrons free.
Energy is released when those neutrons split off from the nucleus, and the
newly released neutrons strike other uranium or plutonium nuclei, splitting
them in the same way, releasing more energy and more neutrons. This chain
reaction spreads almost instantaneously. (

To give you an idea of the power of an atomic bomb,
Hiroshima was hit with the power of 15,000 tons of TNT, while Nagasaki was
blasted with the destructive power of 21,000 tons of TNT.
A hydrogen bomb works differently.
Nuclear fusion is a reaction that releases atomic
energy by the union of light nuclei at high temperatures to form heavier
atoms. Hydrogen bombs, which use nuclear fusion, have higher
destructive power and greater efficiencies than atomic bombs.
Due to the high temperatures required to initiate
a nuclear fusion reaction, the process is often referred to as a
thermonuclear explosion. This is typically done with the isotopes of hydrogen
(deuterium and tritium) which fuse together to form Helium atoms. This led to
the term “hydrogen bomb” to describe the deuterium-tritium fusion
bomb. (
source)
Hydrogen bombs (H-bombs) have been used before.
The first hydrogen bomb was exploded on November 1, 1952 at the small
island Eniwetok in the Marshall Islands. Its destructive power was several
megatons of TNT. The blast, timed at 19:15 GMT,
produced a light
brighter than 1,000 suns and a heat wave felt 50 kilometres away. The
Soviet Union detonated a hydrogen bomb in the megaton range in August of 1953.
The US exploded a 15 megaton hydrogen bomb on March 1, 1954. It had
a
fireball of 4.8 km in diameter and created a huge mushroom-shaped cloud. (

An h-bomb is expected to be 700 times more
powerful than the atomic bomb that was dropped on Hiroshima, during which more than 150,000 people died. But they didn’t die all at
once. Many of them suffered terrible, lingering deaths of agony. Here is the
breakdown of this from a UCLA report.
- Very
large numbers of person were crushed in their homes and in the buildings
in which they were working. Their skeletons could be seen in the debris
and ashes for almost 1,500 meters from the center of the blast,
particularly in the downwind directions.
- Large
numbers of the population walked for considerable distances after the
detonation before they collapsed and died.Large
numbers developed vomiting and bloody and watery diarrhea (vomitus and
bloody feces were found on the floor in many of the aid stations), associated
with extreme weakness. They died in the first and second weeks after the
bombs were dropped.
- During
this same period, deaths from internal injuries and from burns were
common. Either the heat from the fires or infrared radiation from the
detonations caused many burns, particularly on bare skin or under dark
clothing.
- After
a lull without peak mortality from any special causes, deaths began to
occur from purpura, which was often associated with epilation, anemia, and
a yellowish coloration of the skin. The so-called bone marrow syndrome,
manifested by a low white blood cell count and almost complete absence of
the platelets necessary to prevent bleeding, was probably at its maximum
between the fourth and sixth weeks after the bombs were dropped. (source)
Now, multiply the above by 700 times and you’ll have a
good idea of the horrifying affects of a hydrogen bomb. If it were to strike a
major population area in the United States, the death toll would be astounding.
This video shows a comparison of actual atomic and
hydrogen bombs.
How large of an area would
be affected by a hydrogen bomb?
According to the website National Terror Alert, created
by the DHS, these are the distances at which the destruction would occur, using
the Hiroshima bomb as a point of reference.
1 Megaton Surface Blast: Pressure Damage
The fission bomb detonated over Hiroshima had an
explosive blast equivalent to 12,500 tons of TNT. A 1 megaton hydrogen bomb,
hypothetically detonated on the earth’s surface, has about 80 times the blast
power of that 1945 explosion.
Radius of destructive circle: 1.7 miles
12 pounds per square inch
At the center lies a crater 200 feet deep and 1000 feet
in diameter. The rim of this crater is 1,000 feet wide and is composed of
highly radioactive soil and debris. Nothing recognizable remains within about
3,200 feet (0.6 miles) from the center, except, perhaps, the remains of some
buildings’ foundations. At 1.7 miles, only some of the strongest buildings —
those made of reinforced, poured concrete — are still standing. Ninety-eight
percent of the population in this area are dead.
Radius: 2.7 miles
5 psi
Virtually everything is destroyed between the 12 and 5
psi rings. The walls of typical multi-story buildings, including apartment
buildings, have been completely blown out. The bare, structural skeletons of
more and more buildings rise above the debris as you approach the 5 psi ring.
Single-family residences within this this area have been completely blown away
— only their foundations remain. Fifty percent of the population between the 12
and 5 psi rings are dead. Forty percent are injured.
Radius: 4.7 miles
2 psi
Any single-family residences that have not been
completely destroyed are heavily damaged. The windows of office buildings have
been blown away, as have some of their walls. The contents of these buildings’
upper floors, including the people who were working there, are scattered on the
street. A substantial amount of debris clutters the entire area. Five percent
of the population between the 5 and 2 psi rings are dead. Forty-five percent
are injured.
Radius: 7.4 miles
1 psi
Residences are moderately damaged. Commercial buildings have sustained
minimal damage. Twenty-five percent of the population between the 2 and 1 psi
rings have been injured, mainly by flying glass and debris. Many others have
been injured from thermal radiation — the heat generated by the blast. The
remaining seventy-five percent are unhurt. (

But it isn’t just the initial blast you’d have to be
concerned about. The radioactive fallout would affect many more people further
away from the blast during the first week.
1 Megaton Surface Blast: Fallout
One of the effects of nuclear weapons detonated on or
near the earth’s surface is the resulting radioactive fallout. Immediately
after the detonation, a great deal of earth and debris, made radioactive by the
blast, is carried high into the atmosphere, forming a mushroom cloud. The
material drifts downwind and gradually falls back to earth, contaminating
thousands of square miles. This page describes the fallout pattern over a
seven-day period.
Assumptions
Wind speed: 15 mph
Wind direction: due east
Time frame: 7 days
3,000 Rem*
Distance: 30 miles
Much more than a lethal dose of radiation. Death can occur within hours of
exposure. About 10 years will need to pass before levels of radioactivity in
this area drop low enough to be considered safe, by U.S. peacetime standards.
900 Rem
Distance: 90 miles
A lethal dose of radiation. Death occurs from two to fourteen days.
300 Rem
Distance: 160 miles
Causes extensive internal damage, including harm to nerve cells and the cells
that line the digestive tract, and results in a loss of white blood cells.
Temporary hair loss is another result.
90 Rem
Distance: 250 miles
Causes a temporary decrease in white blood cells, although there are no
immediate harmful effects. Two to three years will need to pass before
radioactivity levels in this area drop low enough to be considered safe, by
U.S. peacetime standards.
*Rem: Stands for “roentgen equivalent man.” This is a measurement used
to quantify the amount of radiation that will produce certain biological
effects. (

So, as you can see, a hydrogen bomb puts the destruction
at a whole different level from the nuclear warheads that people expected where
Kim Jong Un’s most devastating weapons. And sadly, this isn’t the only risk.
Could an H-bomb detonated
at high altitude take down the American power grid?
Something that could potentially be even more deadly
during the long-term is a hydrogen bomb that is detonated at high altitude,
which would cause an electromagnetic pulse (EMP) that could devastate the
electrical grid across a wide geographical swath.
And this weekend, Kim Jong Un directly threatened the
United States with such an attack.
The news Sunday morning that North Korea had launched
what appeared to be its sixth nuclear test and most powerful one to date is
troubling enough.
But a statement from the rogue regime took things to a whole new level.
The North said it had tested an H-bomb that was “a multi-functional
thermonuclear nuke with great destructive power which can be detonated at high
altitudes for super-powerful EMP (electromagnetic pulse) attack according to
strategic goals.” (
source)
In such an event, part of the United States could lose
power indefinitely. Our infrastructure and devices would not be repairable.
Everything would require replacement, which could take several years.
NOTE: For an excellent,
non-sensational resource, I recommend anything written by Dr. Arthur T.
Bradley, a NASA scientist and recurring speaker over at Preppers
University. He has written numerous books and articles about the
threat of an EMP. His book, Disaster Preparedness for EMP Attacks and Solar Storms, is a
must read for anyone concerned about the possibility of this type of attack. In
it, he dispels many rumor and myths about such an event and replaces them with
facts based on his research with NASA.
It’s important to note that North Korea does have
satellites that would be capable of an atmospheric detonation that would cause
an electromagnetic pulse. In fact, two of the were over our country as recently
as last month. At the time, Dr. Peter Vincent Pry, executive director of
the Congressional Task Force on National and Homeland Security and chief of
staff of the Congressional EMP Commission, warned:
“The EMP Commission has officially been warning about
those satellites especially now that the (intelligence) community admits that
North Korea can miniaturize warheads,” Pry stated. “Our argument all along has
been that they could make weapons small enough to put on those satellites that
pass over the United States on the optimum trajectory for an EMP attack on
North America.”
“And they would obviously be a basis for a surprise EMP
attack if North Korea wants to commit aggression against South Korea. Or to
blackmail us if we were going to intervene to deliver on our security guarantees
for Japan, South Korea or the Pacific.”
Pry said the satellites are orbiting at the “optimum
height for putting an EMP field over all 48 contiguous United States.”
Pry warned that deploying satellites for the purpose of
an EMP option against the U.S. “is exactly the kind of thing that he (North
Korean leader Kim Jong Un) would do. It would make strategic sense to do
it. We do know that Kim Jong Un is a risk-taker.”
Pry surmised that the North Koreans may be utilizing the
satellites for an attack plan pioneered by the Soviets during the Cold War to
attack the U.S. with an EMP as part of a larger surprise assault aimed at
crippling the U.S. military.
Unlike the Soviet plan, Pry opined, the North Koreans may be seeking to
use an EMP attack to target “our electrical grid and our civilian critical
infrastructure. And they only need one weapon to do that.” (

Zero Hedge reported on this worst-case scenario event:
However, it would probably lead to an unknown number of
indirect deaths as hospitals and essential infrastructure lose power.
“The idea of an EMP attack is to detonate a nuclear
weapon tens or hundreds of miles above the earth with the aim of knocking out
power in much of the U.S. Unlike the U.S. atomic bombs dropped over Hiroshima
and Nagasaki in 1945, such a weapon wouldn’t directly destroy buildings or kill
people. Instead, electromagnetic waves from the
nuclear explosion would generate pulses to overwhelm the electric grid and
electronic devices in the same way a lightning surge can destroy equipment.”
In the worst possible scenario, regional power grids
could be offline for months, potentially costing many deaths as people would
eventually start running out of necessities like food and medicine. Lawmakers
and the US military have been aware of the EMP threat for many years, according
to
WSJ. IN a 2008 report
commissioned by Congress, the authors warned that an EMP attack would lead to
“widespread and long-lasting disruption and damage to the critical
infrastructures that underpin the fabric of US society.”
In a report published last month,
the Hill noted that
the North could choose to carry out an EMP attack on Japan or South Korea as a
more politically acceptable act of aggression. Such an attack could help the
North accomplish its three most-important political goals,
the Hill said.
“North Korea has nuclear-armed missiles and satellites
potentially capable of electromagnetic pulse (EMP) attack. EMP is
considered by many the most politically acceptable use of a nuclear weapon,
because the high-altitude detonation (above 30 kilometers) produces no blast,
thermal, or radioactive fallout effects harmful to people.
EMP itself is harmless to people, destroying only electronics. But by destroying electric grids and other life-sustaining
critical infrastructures, the indirect effects of EMP can kill far more people
in the long-run than nuclear blasting a city.
In this scenario, North
Korea makes an EMP attack on Japan and South Korea to achieve its three most
important foreign policy goals: reunification with South Korea,
revenge upon Japan for World War II, and recognition of North Korea as a world
power.” (

Conventional wisdom tells us that North Korea would be
incredibly reticent to live up to its threats of launching a missile strike,
nuclear or otherwise, on South Korea, Guam, Japan or elsewhere because the
retaliation from the United States would be immediate and ferocious,
effectively destroying the country and killing all of its leadership.
However, if Kim Jong Un’s first strike is a successful
EMP attack against North America, this would largely shut down the ability of
the U.S. to respond. While some elements of U.S. military infrastructure have
been hardened for resilience against an EMP strike, there is no standardization
across the board. Plus, civilian infrastructure is hardly protected, if at all.
The United States and Canada would be in the dark and sitting ducks.
A handful of national security experts and legislators in the U.S. have
attempted to sound the alarm about this troubling vulnerability but have
largely been unsuccessful in getting regulations in place. The utilities
industry claims it’s not its problem, but that of the military’s, something
experts firmly dispute. (
source)
Of course, a miscalculation by North Korea could lead to
a ground strike instead of an atmospheric one, leading back to the first
scenario we discussed. Really, with things so volatile, you should be preparing
for all possible scenarios:
Is the United States
discussing a military response?
General James Mattis, the Secretary of Defense, has
suggested that a military response could be imminent.
“Our commitment among the allies are
ironclad,” Mattis said. “Any threat to the United States or its territories,
including Guam, or our allies will be met with a massive military response, a
response both effective and overwhelming.”
Mattis called on North Korean leader Kim Jong
Un to “take heed” of the UN Security Council’s unanimous position against North
Korea’s nuclear program and again stressed the US military’s position.
“We are not looking to the total annihilation of a country, namely North
Korea, but as I said, we have many options to do so,” Mattis said. (

Don’t be distracted while the United States digs itself
out from under the devastation of Hurricane Harvey and holds its breath
watching the uncertain path of Hurricane Irma. As devastating as those storms
are and could be, we may have even more dire things to worry about.
Do you have knowledge about
nuclear weapons?
My research comes from a variety of experts cited on the
internet, but it’s purely theoretical for me. Do you have more
information?
Please weigh in below in the comments section. Your
information is very welcome. Please let us know where your knowledge comes
from. (Do you/did you work in this field? Do you have a military background? A
scientific background?) We’d love to hear from you.
