SEOUL: A seismic event in North Korea on Friday morning measured by the US Geological Survey with a magnitude of 5.3 appeared to be a nuclear test, South Korea’s meteorological agency said.

The seismic event was detected near North Korea’s known nuclear test site, where it detonated its fourth nuclear device in January. The USGS said the tremor was detected on the surface. Naturally occurring earthquakes strike below ground.
