North Korea Detonates Hydrogen Bomb
Jan 08, 2016

North Korea says it has successfully carried out its first underground test of a Hydrogen bomb on 6 January—a more powerful weapon than an atomic bomb. This one is its fourth nuclear test since 2006 and mark a huge advance in its nuclear capabilities.

Suspicion an underground test had been carried out was first raised after the US Geological Survey detected unusual seismic activity at 10 a.m. Pyongyang time (01:30 GMT) in the north-east of the country. A 5.1 magnitude tremor was detected about 50 km from Kilju city, near the Punggye-ri nuclear site, which was likely not natural. 

  • Bombs of this kind, which rely on nuclear fusion, release far more destructive power than other weapons based on a fission reaction. 

  • If North Korea’s claim is true, the country would have joined the ranks of the world’s thermonuclear powers. 

  • This trial was viewed as further evidence of the steady expansion of North Korea’s nuclear ambitions. 

  • The North Korean regime is now believed to possess up to 20 nuclear weapons–about half of which are loaded onto ballistic missiles. 

  • Last year, North Korea tested a submarine-launched missile and declared its intention of mastering the technology for thermonuclear weapons.

  • North Korea’s apparent aim is to build an arsenal of thermonuclear weapons that could eventually be delivered on long range missiles. 

  • The Taepodong-2 missile, currently in development, could fly as far as the United States.

Difference between Atom Bomb & Hydrogen Bomb

Hydrogen bomb, also known as a thermonuclear bomb, combines hydrogen isotopes under extremely high temperatures to form Helium, in a process known as nuclear fusion. It is more powerful than a conventional atomic weapon: It uses the energy released from the combination of two light atomic nuclei, while an atomic bomb uses the energy released when a heavy atomic nucleus splits, a process known as nuclear fission. American scientists developed the hydrogen bomb, which was first tested in 1952.
