North Korea Detonates It's Biggest Nuclear Test Ever Causing Earthquake Tremor

North Korea has conducted a fifth nuclear test, its most powerful to date, South Korea's military said after monitors detected a 5.3-magnitude "artificial earthquake" near its main nuclear site.

The tremor was recorded at the Punggye-ri nuclear test site at around 9:30 am on Friday, the 68th anniversary of the founding of the North Korean regime.

The last underground detonation at Punggye-ri took place in January, with Pyongyang claiming it was of a hydrogen bomb.
