The US President branded North Korea a ‘rogue nation and a threat’ after Pyongyang said it conducted its sixth nuclear device test. Donald Trump also raised the prospect of attacking North Korea, responding to a question on the issue: “We’ll see.”
NORSAR has recorded signals from an underground nuclear test explosion conducted by North Korea at its Punggye-ri test site on 3 September 2017. NORSAR has estimated the explosive yield at 120 kilotons TNT, based on a seismic magnitude of 5.8. In comparison, the explosive yield of the nuclear bomb dropped on Hiroshima on 6 August 1945 was estimated at 15 kilotons TNT, while the bomb dropped on Nagasaki three days later was 20 kilotons TNT.
The test site in North Korea is located at a distance of 7360 km from NORSAR’s seismic station in Hedmark. Given that the seismic waves take approximately 11 minutes to propagate from North Korea to Norway, the measurements indicate that this explosion took place at 03:30 UTC.
The figure below shows the estimated locations within the Pungggye-ri test site of the five previous tests (red dots). The tests are conducted in the tunnel system inside the mountain. The area of the likely location of the most recent test is indicated in the figure. Some additional work is required in order to estimate a precise location.
North Korea claims that this was a test of a hydrogen bomb; the same claim was made for previous tests. It is not possible from the seismic data alone to determine if this was a test of a hydrogen bomb, but we can say in general that the credibility of the claim increases with increasing explosive yield. Possible leakage of radionuclides may be registered later and may indicate the type of bomb. These data may be available in a matter of weeks, if there is a leakage from the test site.
North Korea has for the first time threatened to wage an EMP attack against the United States. Such an attack has the potential to cause catastrophic damage to North America, Canada, The West and many of it neighbors.
North Korea threatens to wipe out the United States on a regular basis through its state Media. However this is the first time North Korea has openly threatened to use an EMP weapon.
According to the Associated Press shortly after North Korea launched its sixth nuclear test using an H-bomb. The Hermit Kingdom’s leader Kim Jong-un issued a statement through its state run Korean Central News Agency claiming the weapon is a multi-functional.
thermonuclear nuke with great destructive power which can be detonated even at high altitudes for super powerful EMP attack according to strategic goals.
Scott Snyder, senior fellow for Korea Studies and director of the Program on U.S.-Korea Policy at the Council on Foreign Relations, provides an overview of “North Korean Nuclear Threat”—a scenario from CFR’s Model Diplomacy (https://modeldiplomacy.cfr.org), a free multimedia simulation program that engages students through role-play to understand the challenges of shaping U.S. foreign policy in an interconnected world.
Snyder outlines the threat posed by North Korea’s nuclear and missile program, both to its neighboring countries and to the United States. He reviews U.S.-North Korean hostility and the interests of the United States and other countries in the situation on the Korean Peninsula. Snyder concludes by outlining U.S. policy options to confront North Korea’s nuclear development.
North Korea's latest ballistic missile test has renewed discussion at the highest levels of the Trump administration about how military force could be used to stop Kim Jong Un's development of nuclear warheads and ballistic missiles.
"For those who have said, and been commenting about a lack of an military option, there is a military option," national security adviser H.R. McMaster told reporters Friday, adding: "Now, it is not what we would prefer to do."
At the same press briefing, UN Ambassador Nikki Haley acknowledged that if sanctions and diplomatic pressure don't work, the UN may not be able to do much more.
"So, having said that, I have no problem with kicking it to (Defense Secretary) Gen. James Mattis because I think he has plenty of options," she said.
