Description Four wells of groundwater are selected in this study. The location (longitude and latitude) of each observation data (water level) is show in the Excel file. All the observation data comes from the digital observation instruments of those groundwater stations of the China Earthquake Networks Center. The water-level of selected wells are of high quality, and the selection is based on the catalogs provided by provincial earthquake administrations and institutions (China Earthquake Administration, 2004). Besides, the selected well is away from the coast to minimize the effects of ocean tides.
The tidal response analysis of water level: Water level data are observed from May 1st, 2008 to June 30th, 2011, during which two huge earthquakes occurred (the 2008 MW 7.9 Wenchuan earthquake and the 2011 MW 9.1 Tohoku earthquake).

Type Water-level are documented with a LN-3A digital instrument with an accuracy of ≤ 0.2% full scale, resolution of 1 mm, and sampling rate of 1 per minute. In each data file, there are two sequences: the left column is the time (year-month-day-hour-min), and the right column is the water level (unit-m).
Format *.DIG format data can be read directly using MATLAB, et al.
