Test chronology | |
The Democratic People's Republic of Korea (North Korea) conducted its sixth (and most recent to date) nuclear test on 3 September 2017, stating it had tested a thermonuclear weapon (hydrogen bomb).[6] The United States Geological Survey reported an earthquake of 6.3 magnitude not far from North Korea's Punggye-ri nuclear test site.[7] South Korean authorities said the earthquake seemed to be artificial, consistent with an underground nuclear test.[8] The USGS, as well as China Earthquake Networks Center, reported that the initial event was followed by a second, smaller, earthquake at the site, several minutes later, which was characterized as a collapse of the cavity formed by the initial detonation.[9][10]
