| Abstract: | After studying four mathematical methods of extracting the multiparamter non - dimensional precursor informaion of medium, short and impending earthquakes, based on the data of groundwater level,radon in groundwater, earth resistivity, crustal stress, fixed point leveling, connected pipe, clinometer,tensometer and air temperature from 1975 to 1977 at 11 computation points (stations), which were within the range of 250 km around epicenter of the M7. 8 Tangshan earthquake (1976. 7. 28 ), the multiparameter non - dimensional earthquake precursor information is calculated, and by use of Terfi's method the relative importance of four methods is evaluated so as to select the optimal scheme. |
