to make the seismic station in January 2008 - September 2012 borehole strain, borehole tilt, water temperature, geomagnetic precursory observation data of the natural environment, human interference factors such as, observation technology system failures are analyzed research, says DE make ha Taiwan interference factors exist: (1) natural environment interference factors have a man-made lake, blackrock mountain reservoir, on the river and irrigation channels, etc; (2) man-made interference factors have precursor instrument maintenance, zero maintenance, calibration, etc; (3) observation technology design flaws system failure interference factors have lead to power supply failure, poor contact probe or leak, instability of the working state of equipment components, etc。
