(2011)](https://doi.org/10.1029/2010JB007794 \"Frequency characteristics of the response of water pressure in a closed well to volumetric strain in the high-frequency domain\") which this package is named after.\n\n### Open Well\n\nThe first theoretical model for a sealed well responding to seismic displacements is from \n[Cooper, et al. (1965)](https://doi.org/10.1029/JZ070i016p03915 \"The response of well-aquifer systems to seismic waves\").\n\nThis package also includes support for the models in\n[Hsieh, et al. (1987)](https://doi.org/10.1029/WR023i010p01824 \"Determination of aquifer transmissivity from Earth tide analysis\").\n[Rojstaczer (1988)](https://doi.org/10.1029/JB093iB11p13619 \"Intermediate period response of water levels in wells to crustal strain: Sensitivity and noise level\"), and\n[Liu, et al. (1989)](https://doi.org/10.1029/JB094iB07p09453 \"Seismically induced water level fluctuations in the Wali Well, Beijing, China\"), which are based on various sources (i.e., tides, atmospheric pressure, and seismic waves).\n[Wang, et al.
