If the proposed reservoir is substantial in volume or active faults cross near the reservoir area, then potential for reservoir-triggered seismicity (RTS) should be evaluated. RTS is the idea that the added weight of the reservoir or pore pressure distribution increases the frequency of earthquakes in areas of high seismic activity or may cause earthquakes in areas thought to be seismically inactive. RTS has been observed in dams over 100 meters high.
