Abstract: This Paper collects and analyzes all of more than 70 examples with precursors obtained since the observation of earth resistivity in Chlna(in the period of 1987-1988), among which 8earthquakes are with magnitude more than7, 13 with magnitude 6-7, 16 with magnituue 3-6, 34 with magnitude 2-5, The paper also presents the distribution characteristics of time and space of telluric currence anonalies quantity; duration.anomalous amplitude, distributing range of earth resistivity anomar lies; and the empirical regularity for prediction of the three elements of earthquakes.
