Better, nuke the post and reward those who wait to post until a credible, informative story exists.
It is credible. If you read the CNN story there is seismic readings which support the claim at least partially. Plus Japan, South Korea, and the US aren't calling them liars and are being very measured in what they're saying which hints to me that they think something took place.

I've flagged this post and upvoted the BBC & NYT versions.
If this is confirmed, I am really interested to see China's stance. South Korea and Japan are definitely going to raise security concerns. The crazy neighbor now has a gun.
I don't think this changes anything re: South Korea and Japan.
North Korea has a fission bomb for at least 10 years. They don't have small enough warheads or good enough missiles to do anything with them.
The only card the DPRK has in a conventional war with ROK is that they have the ability to destroy Seoul with fairly "dumb" weapons before they are wiped out. Nukes don't change that equation.

Initial seismic reports are pretty underwhelming for a fusion weapon, so maintaining some skepticism on whether this is a significant new capability is probably merited until we get some radiation data.

My first thought after seeing this was, "what if they published the complete design online? I wonder how the major world powers would react."
You can find designs for nuclear bombs by Googling. The hard part is manufacturing the nuclear material.
Their Atomic Bombs had notably low yields [1], suggesting that the designs were poor. I'd be really surprised if they managed to successfully construct a Hydrogen Bomb.

Hydrogen bombs may not be harder to design because the fusion step has so much room for error; IIRC, André Gsponer and Jean-Pierre Hurni's technical report _Fourth Generation Nuclear Weapons_ http://web.elastic.org/~fche/mirrors/www.cryptome.org/2014/0... says that hydrogen bombs are actually much more reliable and hard to get wrong to the point where it's surprising that recent nuclear states like India or Pakistan don't start with h-bombs and work their way down to the trickier a-bombs.
Apparently their last test was also detected at magnitude 5.1, so I suppose that this was probably not an H-bomb.

>On February 11, 2013, the U.S. Geological Survey detected a magnitude 5.1 seismic disturbance,[13] reported to be a third underground nuclear test.[14] North Korea has officially reported it as a successful nuclear test with a lighter warhead that delivers more force than before, but has not revealed the exact yield. Multiple South Korean sources estimate the yield at 6–9 kilotons, while the German Federal Institute for Geosciences and Natural Resources estimates the yield at 40 kilotons.[15][16][17]

The 5.1 earthquake for this bomb would suggest a smaller explosion than the bombs at the tail end of WW2, however that depends on a lot of things. Looking at this list it would suggest about a ~600 ton explosion http://self.gutenberg.org/articles/richter_magnitude_scale
If I had to guess the seconds stage of their bomb significantly underperformed / didn't fire if it was a true h-bomb

I'm not well schooled in nuclear bombs. What's the payload, how does this compare to their previous tests, and what's next?

A regular 'atomic' bomb is a fission reaction. A hydrogen bomb uses a fission bomb to cause a nuclear fusion reaction. H-bomb = much more powerful.
Most of the energy from large H-bombs still comes from fission.
You can surround the fusion stage with natural uranium. While natural uranium has to much U-238 to undergo a runaway chain reaction, the fission reaction emits enough high energy neutrons to induce a significant fission reaction.

Here's a New York Times report: http://www.nytimes.com/2016/01/06/world/asia/north-korean-tr...
No real detail, though. Artificial earthquake detected. North Korea apparently claims a successful hydrogen bomb test.

What a timing. South Korea's Left and Right haven't been polarized in years since South Korea and Japan settled on Comfort Women tragedy. In less than a month, Koreans are now faced with this news that will surely erupt new discussions on how to deal with North Korea.
Yep. Japan is marching towards peace with Russia as well...I suspect Kim is getting nervous.
Damn their infernal terminal. Weirdest social network ever.
Congratulations to NK for their first successful test!
Well, on the bright side, they've probably killed more of their own people through allocating resources to such a thing instead of food and whatnot than they'll ever manage to take out with the weapon.
How is that the bright side? Those people are innocent! It's not as though you can blame them for being born in North Korea! (And those who starve are guaranteed to not be those who are in power.)
Plus, I'm not sure to what degree actual starvation is currently a problem in North Korea. It's probably more about e.g. health care not being modern?

No, it's not about just about health care. They literally have massive food shortages, particularly outside Pyongyang.

Well I for one have no beef with starving North Korean peasant farmers. So there is no bright side as far as I am concerned.
It's also little to no consolation that the Kims regularly purge the military ruling classes as well, while the people starve.
