Summary: A joint Chinese and South Korean study in Science says North Korea’s five underground nuclear explosions at Punggye-ri (2013–2017) altered regional geology and triggered a chain of seismic events. The researchers report the activity activated ancient fault lines extending toward a major volcano about 100 km from the China border.
WHO: Joint Chinese and South Korean study published in Science
WHAT: Study links North Korea’s 2013–2017 nuclear tests at Punggye-ri to seismic events that activated ancient fault lines toward a major volcano near the China border.
WHEN: Jan 1, 2017
WHERE: China border region
WHY: The study attributes the seismic chain and fault activation to the underground nuclear explosions conducted between 2013 and 2017 at the Punggye-ri test site.
