Influence of aquifer thickness on the amplitudes of seismic and EM wave-fields. We calculate the absolute amplitudes of horizontal total components and vertical components of the seismic and EM wave-fields simulated for the receiver located at (− 80,890, 8680, 0.1) m in the (modified) seven-layer half-space models, where the aquifer thickness is set to be h = 30, 80, 130, 180 or 230 m, respectively. The artificial scattering effect is considered, and the artificial scattering conversion coefficient is set as Cst = 0.6
