A 6.3 magnitude of earthquake shook North Korea on Sunday, prompting fears that Pyongyang has conducted another nuclear rest, the Telegraph reported.
As per the China's Earthquake Administration, North Korea has carried out its sixth nuclear test.
The administration had earlier detected a quake in North Korea, of 5.2 magnitude.
Eight minutes after the first quake, the administration reported about another quake occurred in North Korea of magnitude 4.6, which has been described as a 'collapse'.
The coordinates of the two quakes were almost identical, according to figures provided by the administration.
Previous recent tremors in North Korea have been caused by nuclear tests.
This comes amid escalated tension after a series of tests by the North Korean regime, including one which saw a missile fly over Japan.
