The explosion was heralded by a 6.3-magnitude earthquake felt in Yanji, China, about six miles (10km) from North Korea’s Punggye-ri nuclear test site in the north-east of the country. The previous nuclear blast in North Korea is estimated by experts to have been about 10 kilotons. The agency later said the second tremor could have been caused by a cave-in near the underground nuclear test site. Kim visited the country’s Nuclear Weapons Institute and “watched an H-bomb to be loaded into new ICBM”, KCNA said. Kim had “set forth tasks to be fulfilled in the research into nukes”, KCNA said, but it made no mention of plans for a sixth nuclear test.
