North Korea conducted a 'successful' hydrogen bomb test, Pyongyang has confirmed. The thermonuclear weapon triggered a massive 5.1 magnitude earthquake when it exploded at 10am local time on Wednesday.
平壤方面已经证实，朝鲜成功的进行了氢弹试验。在当地时间周三上午10点，这个热核武器的爆炸引起了5.1级的巨大地震。
It comes months after leader Kim Jong-Un suggested his country had developed such a weapon, which is lighter yet even more powerful than other nuclear bombs.
几个月前，朝鲜最高领导人金正恩曾表示朝鲜已经研制出这种较其他核武器更轻而破坏力更大的武器。
'The republic's first hydrogen bomb test has been successfully performed at 10:00 am on January 6, 2016, based on the strategic determination of the Workers' Party,' a state television news reader announced five-and-a-half hours after the blast.
朝鲜中央电视台在爆炸发生五个半小时后宣布：“2016年1月6日上午10点，基于劳动党的战略决定，共和国的第一枚氢弹试爆成功。”

The successful detonation marks a major step in North Korea's nuclear development and is bound to cause considerable anxiety to neighbouring countries.
这次试爆的成功标志着朝鲜核武器技术的发展迈上了一个新台阶，而这也势必给邻国带来很大的恐慌。
Last month, Kim Jong-Un had suggested Pyongyang had already developed a hydrogen bomb - although the claim was greeted with scepticism by international experts.
上个月，金正恩曾表示平壤已经开发出一枚氢弹，尽管这一言论受到国际专家的普遍质疑。
North Korea has hinted before at the possession of 'stronger, more powerful' weapons, but Kim's remarks were believed to be the first direct reference to an H-bomb.
朝鲜方面之前已经暗示其拥有“更强，更有破坏力”的武器，但金正恩的讲话被认为是第一次直接提到了氢弹。
Prior to being confirmed, Chinese and South Korean officials both said there were early indications the tremor was man-made, with South Korea's Met Agency saying it was 'highly likely' the earthquake was caused by nuclear testing.
在爆炸被证实之前，中国和韩国官方均称，初步迹象显示这次地震是人为的，韩国相关机构还表示，这次地震“极有可能”是由核试验引起的。
