中科院海洋所高翔博士与其合作者研究发现光滑洋壳的俯冲较粗糙洋壳的俯冲更易产生毁灭性的海底大地震。他们以热流实测数据为依据,首次发现有大地震发生的俯冲断层相对于蠕变滑动的俯冲断层生成更少的摩擦热,说明有大地震发生的俯冲断层强度更弱。右图展示了该项研究的俯 Dr Gao Xiang, from the Institute of Oceanology, CAS, and his collaborator found that the subduction of the smooth oceanic crust is more prone to the devastating seafloor earthquake than the subduction of the rough oceanic crust. Based on the measured data of heat flow, they found for the first time that the subduction faults occurred in large earthquakes generate less frictional heat than the creep sliding subduction faults, indicating that the weakening of the subduction faults occurred in the large earthquakes occurred.
