This was the largest hydrogen bomb ever tested, is North Korea seriously claiming it has a weapon a thousand times more powerful than that:-
The blast yield from that was as you can see around 50 megatons, so North Korea is claiming it has a weapon that can produce a yield of 50,000 or so megatons. Just a few wee problems with this, if you read the history of the hydrogen bomb you will see why the US and CCCP both didn’t bother scaling them up any further.
The research for this piece of scare-mongering is hilarious, or should I say lack of research. Firstly a bomb that powerful would be ineffective as a great deal of the blast would radiate back into space which is why during the Cold War people stopped building bigger and bigger bombs. Tsar Bomba was as big as it ever got and even it was more of a show of force than a real usable weapon.
However wrote this for the article needs to go and do some research:-
The “H-bomb” is a weapon unlike any other — it is believed to be 1000 times more powerful than the atom bomb dropped on Hiroshima. Countries including China, the US and Russia have hydrogen bombs but have never used one.
No the US and CCCP never used one in war but both tested them. I think H-bombs falling on Manhattan is probably not a major concern that Americans needs to start sweating about.
