چکیده
|
Recently developed numerical simulation technique can simulate the coupled seismic and electromagnetic signals for a double couple point source or a finite fault planar source. besides the source effect,the simulation results showed that both medium structure and medium property could affect the coupled seismic and electromagnetic signals. the waveform of coupled signals for a layered structure is more complicated than that for a simple uniform structure. different from the seismic signals,the electromagnetic signals are sensitive to the medium properties such as fluid salinity and fluid viscosity. therefore,the co-seismic electromagnetic signals may be more informative than seismic signals. © 2015 the japan academy.
