Abstract: The Jingle well is one of the wells that belong to the monitoring network of ground-water level in Shanxi Province. Data from this well show that ground-water variation has been experienced 3 high level stages for 14 years from 1983 to 1996. The high water levels are partially caused by rainfall, but mostly reflected the increase of the regional stress field, because the 3 time periods with high water level are consistent with the active periods of moderately strong earthquakes in North China.

Key words: Water level, Seismicity, Jingle well in Shanxi Province
