Title Water level data used for fracture analysis obtained from CENC (China Earthquake Networks Center)
Creator Yan Zhang
Subject Groundwater observation data (water level)
Publisher Xiukuan Zhao
Description 5 wells of groundwater are selected in this study. The location (longitude and latitude) of each observation data 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.

Date a-during the 2008 Wenchuan earthquake, data observed are from February 1st, 2008 to August 31th;
b-during the 2011 Tohoku earthquake, data observed are from December 1st, 2010 to June 30th, 2011.
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.
Format the *.DIG format data (can be read directly using the software of MATLAB, et al.) has been stored in each file. 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) or the barometric pressure (unit-hPa).
