	Study on the generation mechanism of Co-seismic electric signals
	Huang, Qinghua
	2004
英文摘要	An electromagnetic fault model, which considered the compensation of piezoelectric effect and the dislocation theory of fault, was presented to deal with the reported co-seismic electric signals. Charges are assumed to be induced by the stress changes associated with an earthquake. The stress-induced charges are quantified by the charge density as a function of the polarization, which can be calculated using a piezoelectric model and an analytical solution of seismic stress. The theoretical charge distribution around the Nojima fault, which moved at the 1995 Kobe earthquake (M=7.2), was obtained. The co-seismic electric field consistent with that observed at the Kobe earthquake was estimated as the field due to the charges, which compensate the piezoelectric charges. ? 2004 IEEE.; EI; 0
