» » North Korea raises alarm - tests hydrogen bomb >>



شمالی کوریا  نے بڑی طاقتوں کے لئے خطرے کی گھنٹی بجادی،تباہ کن  ہائیڈروجن بم کا تجربہ کردیا
شمالی کوریا نے اعلان کیا ہے اس نے کامیابی کے ساتھ ہائیڈروجن بم تیار کیا ہے ۔ اور بدھ کے اعلامیے کے مطابق کوریا نے اس کا کامیاب تجربہ بھی کیا ہے۔  تجربہ جوہری ٹیسٹ سائیٹ کے قریب کیا گیا۔ سراکاری میڈیا کے مطابق مذکورہ جگہ کے اطراف میں دور دور تک 5.1  میگنی چیوڈ کی شدت کا زلزلہ محسوس کیا گیا۔  بعد ازاں اعلان کیا گیا کہ یہ زلزلہ نہیں تھا بلکہ ہائیڈروجن بم کا تجربہ تھا۔ 
کوریا نے  2006 سے اب اتک  تین زیر زمین ایٹمی تجربات بھی کئے ہیں۔  ہائیڈروجن بم  میں فیوژن استعمال ہوتا ہے جس سے دھماکہ  روایتی ایٹم بم کے مقابلے میں زیادہ تباہ کن ہوتا ہے۔ 
جنوبی کوریا کے صدر نے تجربے کی مذمت کرتے ہوئے کہا کہ ہماری حکومت شمالی کوریا  کے اس رویے کی سخت مذمت کرتی ہے ۔  جس میں وہ امریکی اور بین الاقوامی برادری کی طرف سے بار بار انتباہ کو نظر انداز کررہا ہے اور یہ واضح طور پر اقوام متحدہ کی قراردادوں کی خلاف ورزی ہے۔ (مانیٹرنگ ڈیسک)



Opponents rush to condemn statement that, if confirmed, would mark fourth time Pyongyang has exploded a nuclear bomb.

North Korea said it has conducted a hydrogen bomb test in a surprise announcement that caused regional tension and drew swift condemnation from opponents. 

If confirmed, the test would be the fourth time Pyongyang has exploded a nuclear device.

South Korean intelligence officials and several analysts, however, reportedly questioned whether Wednesday's explosion was indeed a full-fledged test of a hydrogen device.

There was no radiation detected at Japanese monitoring posts.

Still, before the announcement was made on state television, South Korea's meteorological agency said that a 5.1 magnitude earthquake was detected near a known test site in the secretive and isolated state.

South Korea's presidential office held an emergency meeting and later said that the government would take all possible measures to respond to its neighbour and long-time foe's actions.

"Our government strongly condemns North Korea ignoring repeated warnings from us and the international community and pushing ahead with the fourth nuclear test, which clearly violated the UN resolutions," Cho Tae-yong, a senior security official at the South Korean presidential office said.

What exactly are hydrogen bombs?
Hydrogen bombs are more sophisticated than atomic bombs and can be thousands of times more powerful.
 
With an atomic bomb, uranium or plutonium is split in a process known as nuclear fission.
This explosion is used in a hydrogen bomb to trigger a secondary explosion, known as nuclear fusion.
 
Nuclear fusion occurs when lighter elements join together, producing temperatures of up to 400 million Celius and powerful shockwaves.
 
Given the technical challenge of building a H-bomb, one theory is that North Korea may have actually tested a so-called "boosted" bomb.
 
"Boosted" nuclear weapons use a small amount of lithium deuteride to energise the reaction, making them more powerful, but they are not considered full hydrogen explosions.
The UN Security Council called an emergency meeting for Wednesday, diplomats said, as both neighbouring countries and world powers scrambled to issue stern statements.

China's foreign ministry said that it had no advance knowledge of any test and that it firmly opposed Pyongyang's action.

Hua Chunying, a ministry spokeswoman, said at a daily news briefing that Beijing - one of North Korea's only allies - would work with the international community on the denuclearisation of the Korean peninsula.

The US government said that it could not confirm a nuclear test but that it would respond appropriately to what it called North Korean "provocations" and that it would continue to protect its allies in the region. 

"We have consistently made clear that we will not accept [North Korea] as a nuclear state," a State Department statement said.

Japanese Prime Minister Shinzo Abe called the announcement a threat to his nation's safety. 

Abe told reporters: "We absolutely cannot allow this, and condemn it strongly."
