朝鲜核试验引发地幔山断层持续复活

Xingli Fan1*†, Kwang- Hee Kim2*†, Su Young Kang3, Lanbo Liu3,4, Jie Song1, Yujin Sohn2, Hyeong- Tae Jou3, Qi- Fu Chen5,6, Le Li7, Lian- Feng Zhao5,6, Yuan Wang6,8, Tianyao Hao6,8 Underground nuclear explosions typically produce short- lived seismic sequences that decay rapidly after testing ceases. by contrast, seismicity near the punggye- ri nuclear test site at mt. mantap in the Democratic people’s republic of Korea has persisted and intensified for years after the final large- yield explosion in 2017, evolving from diffuse activity to spatially organized distribution along fault- controlled structures. Analysis of 17 years of continuous waveform data reveals a progressive increase in seismicity and delayed reactivation of shallow faults. …
