Seismic activity reported in area of previous North Korea nuclear tests

Source: CNN

The U.S. Geological Survey reported a seismic disturbance in northern North Korea on Tuesday, centered near the site of the secretive regime's two previous nuclear tests.

The area around the reported epicenter of the magnitude 4.9 disturbance has little or no history of earthquakes or natural seismic hazards, according to U.S. Geological Survey maps. The disturbance took place at a depth of about 1 kilometer, the USGS said.


There were no initial reports concerning the activity on the North's state-run Korean Central News Agency on Tuesday.

1. I just saw that over on USGS

and wondered the same thing.

That part of the country is not uninhabited. I hope it was an underground test if it was one.

If it was, they're getting better at it. The last one was rather a fizzle.

This was one of my biggest objections to our involvement in Iraq.

3. North Korea Appears to Test Nuclear Device

By EVAN RAMSTAD

SEOUL—North Korea appeared to have exploded a nuclear device Tuesday, its third experimental detonation in a long effort to build weapons of mass destruction that the U.S. and other countries consider a serious threat.

An "artificial earthquake" was detected at 11:57 a.m., according to authorities in South Korea who attributed the seismic activity to the northeastern area of North Korea where it previously detonated nuclear devices in October 2006 and May 2009.

North Korea made no immediate statement. Its authoritarian regime gave several explicit warnings since Jan. 24 that it was planning to detonate a nuclear explosive.

Even before those statements, diplomats and observers in other countries had considered such an explosion likely as Pyongyang appeared to be repeating a pattern of provocative actions seen before the previous explosions.

Maybe another low-kiloton (1-4 kt) fizzle?

7. My theory

They are having problems developing a reliable implosion device.
Note - not an expert, do not play one on TV, did not stay at Holiday Inn Express last night...

I seem to recall that while it is possible to build a bomb using the "Little Boy" gun design with Plutonium, the gun barrel would have to be too large to put in a practical, deliverable weapon. But if the aim is just to get a nuclear explosion and you have a deep mine shaft to work with, I think it might be practical to set off a rather inefficient crude device. It would not be something you could put on a missile, but it might fit in a large shipping container.

8. BBC: North Korea 'Earthquake' Amid Nuclear Test Fears

The US Geological Survey said it had detected a tremor with a 4.9 magnitude.

South Korean media also reported a "man-made earthquake" in its northern neighbour.

North Korea said last month it was planning to carry out its third nuclear test - despite a threat from the UN Security Council of "consequences".

The USGS said the quake occurred at a depth of 1km. It put the epicentre close to North Korea's known nuclear test site in the northeast of the country.

China's Earthquake Administration described it as a "suspected explosion", AFP reported. Japan's Meteorological Agency said the tremor was "different from a normal earthquake".

9. "Nuclear Test Detected" in North Korea (UN)

A United Nations Security Council diplomat says there has been a nuclear test in North Korea after seismic activity was detected in the country's north-east.

Pyongyang has been threatening a nuclear test for weeks, despite warnings of severe repercussions from the UN Security Council.

South Korean officials said a 4.9-magnitude tremor was detected just before midday local time, but they are almost certain it was not an earthquake.

"We've been informed by the South Koreans that there's been a (North Korean) nuclear test," a UN Security Council diplomat said on condition of anonymity

22. David Sanger- NYT: "North Korea Confirms It Conducted 3rd Nuclear Test"

WASHINGTON — North Korea confirmed on Tuesday that it had conducted its third, long-threatened nuclear test, according to the official KCNA news service, posing a new challenge for the Obama administration in its effort to keep the country from becoming a full-fledged nuclear power.

The KCNA said it used a “miniaturized and lighter nuclear device with greater explosive force than previously” and that the test “did not pose any negative impact on the surrounding ecological environment.

Preliminary estimates by South Korea suggested the test was much more powerful than the previous two conducted by the North.

-snip-

It may take days or weeks to determine independently if the test, was successful. American officials will also be looking for signs of whether the North, for the first time, conducted a test of a uranium weapon, based on a uranium enrichment capability it has been pursuing for a decade. The past two tests used plutonium, reprocessed from one of the country’s now-defunct nuclear reactors. While the country has only enough plutonium for a half-dozen or so bombs, it can produce enriched uranium well into the future.

24. UN Security Council holds emergency meeting on DPRK nuclear test

2013-02-12 23:06:48

UNITED NATIONS, Feb. 12 (Xinhua) -- The UN Security Council met behind closed doors Tuesday morning in an emergency session on the latest nuclear test conducted by the Democratic People's Republic of Korea (DPRK).

South Korea, which holds the rotating council presidency for February, called the meeting.

UN Secretary-General Ban Ki-moon has condemned the test, saying it is "a clear and grave violation" of the relevant Security Council resolutions.

In a statement issued here by his spokesperson early in the day, Ban said "it is deplorable that Pyongyang defied the strong and unequivocal call from the international community to refrain from any further provocative measures." ...

25. North Korea: Nuke test just a "first response" aimed at U.S.

Updated 11:02 a.m. ET

PYONGYANG, North Korea North Korea said the atomic test it conducted Tuesday in the remote, snowy northeast was merely its "first response" taken with "maximum restraint," in response to what it called U.S. threats, and said it will continue with unspecified "second and third measures of greater intensity" if Washington maintains its hostility ...

The Office of the Director of National Intelligence confirmed the test Tuesday, saying in a statement: "The U.S. Intelligence Community assesses that North Korea probably conducted an underground nuclear explosion in the vicinity of P'unggye on February 12, 2013. The explosion yield was approximately several kilotons. Analysis of the event continues." ...

CBS News foreign affairs analyst Pamela Falk reports that China's backing of new sanctions after the North's December rocket launch is a strong indication that the Security Council will be able to pass a tough new resolution. There is new leadership in China, South Korea, North Korea and Japan and there is an increasing concern in the international community that Pyongyang's nuclear test could destabilize the region ...
