North Korea's 2017 Nuclear Test Triggers Years of Seismic Activity, Study Finds

A study in Science reports that the 2017 nuclear test at Mount Mantap caused persistent seismic activity around the Punggye-ri test site for years, contrary to typical aftershock patterns. The mechanism remains unclear, puzzling researchers. This suggests potential long-term geological instability at the site, which could affect future monitoring and regional safety assessments.
