在日本中部松下，2883立方米的城市水被抽入一口1800米深的井中。泵压为50至14巴，在注液开始几天后，距离油井2至4公里处开始发生一系列微震。对这些地震的详细调查证实，这种异常的地震活动是由注水引发的。大部分供水似乎都是通过松下地震断层渗入的。断裂带的本征渗透率估计为0.01-0.1达西，这是裂隙岩石的合理渗透率。
City water, amounting 2883m3, was pumped into a well of 1800m deep at Matsushiro, central Japan. The pumping pressure was 50 to 14 bars, Several days after the start of the fluid injection, a series of microearthquakes commenced two to four kilometers away from the well. Detailed investigations of those earthquakes confirmed that the unusual seismic activity was triggered by the water injection. Most of the supplied water seems to have permeated through the Matsushiro earthquake fault. Intrinsic permeability of the fault zone was estimated as 0.01-0.1 darcy, which are reasonable values for fractured rocks.
