| Abstract: | In this study,72 fixed precursor observation items in eastern China area are collected and processed.To each observation item,the earthquake information are calculated separately and combined into one earthquake synthetic information time series.By analyzing the predication efficacy of the time series to Ms≥5.0 earthquakes,this paper gives the short-term synthesis predication index and method to Ms≥5.0 earthquakes in eastern China. |

| Keywords: | precursor information quantity time series prediction efficiency |
