The mechanisms of the seismic-electromagnetic phenomena attracted as precursors of short-term earthquake forecast have been suggested, however, it is still incompletely understood. Our results showed that the fracture by fault motions could produce the surface charges on the fault. It proves that the electromagnetic abnormalities by the fault motions may also be observed through the surface charging mechanism. Therefore, our study supports that the surface charging mechanism is plausible.
