North Korea conducted an underground nuclear bomb test late Monday.

It happened near the site of two other confirmed tests according to a United Nations Security Council diplomat.

The U.S. Geological Survey says it detected a magnitude 4.9 earthquake centered near the site of the secretive regime’s previous underground nuclear bomb tests.

Monday’s test reportedly had the power of the bomb dropped on Nagasaki, Japan during World War II.

North Korea said Thursday it planned to carry out a nuclear test and more long-range rocket launches, all of which it said are a part of a new phase of confrontation with the United States.
