Quake in North Korea Signals Potential New Nuclear Test

South Korea says the 5.6 magnitude quake was artificial

(SEOUL) — South Korea’s Joint Chiefs of Staff says a magnitude 5.6 quake in North Korea was artificial and it’s analyzing whether the North conducted a nuclear test.

It says it detected a seismic wave from 12:34 p.m. to 12:36 p.m. around Punggyeri, North Korea.

The quake came just hours after North Korea claimed that its leader has inspected the loading of a hydrogen bomb into a new intercontinental ballistic missile.
