瑞士苏黎世联邦理工学院研究小组最近发表于《Nature Geoscience》2015年第8期的文章称,2011年日本大地震后,发震区域的断层应力恢复速度高于预期,致使板块界面的应力状态在短短几年内就恢复到了地震之前的水平。但是,由于在该大型俯冲区没有观测到应力状态的空间变化,因此很难预测未来地震的位置和范围。目前,对大型俯冲地震事件的模拟经常假设俯冲带是分区段的,并且地震因持续的
A recent article by the Federal Institute of Technology in Zurich, Switzerland, published in Nature Geoscience, No. 8, 2015, said that the stress recovery in the seismogenic area was higher than expected after the Great Japan Earthquake in 2011, resulting in a short stress state at the slab interface Within a few years to restore the level before the earthquake. However, since no spatial changes in stress state are observed in this large subduction zone, it is difficult to predict the location and extent of future earthquakes. At present, simulations of large-scale subduction events often assume that the subduction zone is subdivided and that the earthquake is sustained by
