Nuclear Tests Caused Long-Term Earthquakes in North Korea
Research by Chinese and South Korean scientists indicates that underground nuclear tests conducted by North Korea triggered earthquakes that persisted for years after the final test in 2017. The study, published in Science, found that explosions at Mount Mantap disrupted tectonic plates, causing seismic activity along fault lines that continued until measurements in 2025. Using remote seismographs, researchers detected tremors reaching over magnitude 3. Experts note that human intervention can influence underground stress, similar to effects seen in Groningen and Oklahoma.
