| Abstract: | Resistivity measurement with an active source has been practised for thirty years at an enormous number of station in China. Resistivity decreases of several percent, which began 2～3 years prior to the Tangshan earthquake and other events and gradual increases afterward were observed. These anomalous variations were larger than their background fluctuations and hence statistically significant. Resistivity decreases were generally seen first and larger at stations close to epicenters and later and smaller |
