Changes in the permeability of a fault zone are dependent upon the frequency of seismic waves, and is an important phenomenon whose mechanisms have not be completely elucidated to date. In this study, the tidal response of water level in well Chuan06 was considered as an indicator of the permeability of the fault zone, and the sensitivity of permeability changes to earthquakes with different epicentral distances were investigated. The results suggested that the permeability change induced by seismic waves is frequency dependent. In addition, based on the mechanisms of permeability changes induced by the seismic waves, the difference in sensitivity may be attributed to the different sizes of the fractures in the fault zone. These findings are likely to contribute to an understanding of hydrogeological responses and seismic activity induced by the earthquakes.

断层带对不同地震渗透率变化的敏感性：可能取决于地震波频率的证据

断层带渗透率的变化取决于地震波的频率，是一种重要的现象，其机理至今尚未完全阐明。在这项研究中，川06井水位的潮汐响应被认为是断层带渗透性的指标，并且研究了渗透率变化对不同震中距离的地震敏感性。结果表明，地震波引起的渗透率变化与频率有关。另外，基于地震波引起的渗透率变化的机制，敏感性的差异可以归因于断层带中裂缝的不同大小。
