South Korea’s weather agency detected a 2.7 magnitude earthquake near the Punggye-ri – NNorth’s nuclear test site.
“I think the Punggye-ri region is now pretty saturated. If it goes ahead with another test, we risk radioactive pollution,” the head researcher at Korea Seismological Institute said.
Friday’s quake is the country’s fourth since underground nuclear tests in Punggye-ri region took place. Earlier on Sept 3, there was a quake measuring 6.3 in magnitude.
North had claimed it’s last test was a Hydrogen Bomb and US Intelligence has determined the blast was 10 times greater than that of nuclear bomb dropped over Hiroshima at the end of World war II.
The Friday quake wasn’t man-made, exerts said, meaning the nuke test seriously damaged the tectonic plate structures in the area, most likely causing the subsequent quakes.
The Punggye-ri region is a mountainous stretch where earthquakes don’t naturally occur.
