| 摘 要： | 根据一些学者的岩石力学实验结果证实岩石在大破裂前能够产生一种长周期、小振幅的低频事件,并依此来解释大震前井水位长周期事件的物理机制.研究结果表明,大震前井水位长周期事件反映了震源的内部信息,是大震前断裂失稳扩展前预扩展所产生的一种波,是震源成核过程的反映.

| Abstract: | The results of rock mechanical tests, made by some scientists, verify that rock could generate some event with longperiod and low amplitude, which are used to explain physical mechanism of long-period event on well water level before strong earthquake. The result shows that long-period event on well water level before strong earthquake reveal some information interior the seismic source, being wave generated by pre-extension before an extension as the stability of a fault is getting off before an strong earthquake and related to the nucleus formation of the seismic source. |
