North Korea's Nuclear Testing May Have Triggered Hundreds of Earthquakes over Several Years

The underground explosions carried out by North Korea between 2006 and 2017 reactivated faults that remained seismically silent for decades and triggered an activity that increased over the years.
After North Korea detonated its largest nuclear device under Mount Mantap in 2017, scientists were not surprised to detect a few earthquakes immediately after the underground test. A massive explosion fractures and deforms the surrounding rock, usually triggering small lines that fade quickly as the bark adjusts. But, years later, the earth's crust around the Punggye-ri test site was still agitated, according to a study published on Thursday in …
North Korea's nuclear testing may have triggered hundreds of earthquakes over several years
Between 2006 and 2017, North Korea conducted six underground nuclear tests at its vast testing site at Mount Mantap in North Hamgyong province. Typically, underground explosions trigger an intense burst of minor earthquakes that die down once testing stops. But geologists have detected far more seismic activity after the final detonation, and it has persisted for years.
Subterranean nuclear tests seem to be able to change the Earth's crust years after detonation. On the North Korean Mantap, seismic activity did not decrease after the last test of 2017, but continued to increase over years. The quakes increasingly concentrated along two fault zones, which were reactivated by the explosions after the analyses. Busan (South Korea). After underground explosions occur [...] The article Nuclear weapons tests in North…
