To unerstand precursory process before seismic fault slip , this work focuses on earthquake nucleation process on a fault plane through numerical simulation 摘要为了把握断层上地震的前兆规律,对连续介质中断层面上的地震成核过程进行了数值模拟研究。
Following the idea of coseismic stress - triggering , coseismic strain steps recorded by borehole strainmeters are used to study coseismic stress - triggered fault slips 摘要沿着同震应力触发的思路,提出了利用钻孔应变观测记录的同震应变阶反演同震应力触发断层活动的方法。
This predictability most likely stems from the fact that water flowing from below subduction zones may exert significant control over when and where these faults slip silently 这样的可预测性,很可能来自于隐没带下方所流出的水,它对于何时、何地会发生无声的断层滑动,可能具有相当大的操控力。
The importance of deciphering fault slip is difficult to overstate because when faults slip quickly , they can cause immense damage , sometimes at a great distance from the source 要去了解、解释断层滑动的重要性是无庸置疑的,因为一旦断层快速滑动,将会造成巨大的灾情,有时发生位置甚至离震源还有一大段距离。
