North Korea said Pyongyang detonated a hydrogen bomb with “perfect success”, adding that the device was capable of being loaded onto its long-range missiles.
North’s State news agency said the two shallow earthquakes that shook the country today were caused by the hydrogen bomb test.
This comes just hours after it said it had developed an advanced hydrogen bomb that possesses “great destructive power”. According to the agency, the North said it can now successfully mount a hydrogen bomb on an Intercontinental Ballistic Missile (ICBM).
The US Geological Survey was first to report an earthquake in North Korea today, citing a first most powerful tremor of 6.3 magnitude with a depth of 23 kilometres, which occurred at 11.30 a.m. local time.
China later said it had also detected a second quake of 4.6 magnitude in North Korea. A statement on the China’s Earthquake Administration said the second tremor, which it termed a “collapse”, came eight minutes after the first quake and struck 75km north northwest of Kimchaek.
Japan lodged a formal protest with Pyongyang after a major explosion at the isolated nation’s main test site. Japanese Prime Minister Shinzo Abe said, a sixth nuclear test by Pyongyang is absolutely unacceptable and could not be tolerated.
Talking to reporters in Tokyo, Japanese foreign minister Taro Kono said, after examining information from the weather agency and other information, Japan government concludes that North Korea conducted a nuclear test.
He said, the government registered a protest with the North Korean embassy in Beijing prior to the confirmation, calling any test extremely unforgivable. National news agency Yonhap said a meeting of South Korea’s National Security Council has been convened.
