Monitors report unusual seismic activity in North Korea

SEOUL, South Korea (AP) — A European monitoring agency is reporting a 5.0 magnitude quake near North Korea’s northeastern nuclear test site. There was no immediate confirmation of a nuclear test, which such seismic activity has previously indicated.

South Korea’s Defense Ministry said Friday it could not immediately confirm the cause, and the country’s weather agency said it was analyzing what might have happened. But the U.S. Geological Service reported an “explosion” in the area.

North Korea conducted its fourth nuclear test earlier this year, part of its push for a nuclear-armed missile that could one day reach the U.S. mainland.
