The telluric resistivityanomaly of moderate strong earthquake has a complicated feature, the length of the anomaly duration is only 60-90 days, the amplitude of the anomaly is 1-2%.
Parameters of apparent resistivity, impedance phase, and anomaly phase can be acquired.

The induced polarization anomaly is character of high in chargeability and low in electrical resistivity which is consistent with the electrical property of copper ore-body.
