Abstract: The paper described a new method of sif ting index-“ Comparing-Screening Method” to selectsei smological indices through sif ting more than 80 seismological parameters and making several tests of stability. We extract P-value of seismological precursory comprehensive predictio nindex, then develop a new method for the seismological quantitative integrated prediction (SQIP). Meanwhile, we study PP-v alue of no n-seismolo gical precurso ry index in earthquake prediction. The study follows the trail of anomalous behavior seismic activi ty with the dynamic thought to determine the strong earthquake location of medium-a nd short-term. Eachitem of precursory observ ational dataist ransformed to unified non-dimensional seismic information with the principle of mathematical-physical sciences. The R of prediction evaluation obtained is 0.66 in the example of the space-time scanning in North China. A certain practicabi lity has been showed.
