Fig. 8From: Semi-analytical solutions of seismo-electromagnetic signals arising from the motional induction in 3-D multi-layered media: part II—numerical investigationsSynthetic recordings of a electric field component Ex and b magnetic field component Bx, which are induced by the direct P waves and filtered by a Hanning function at \(0.72 < f < 0.88\) Hz. c The amplitude decay curves of the simulated EM signals (Ex and Bx) in comparison with the theoretical decay curve determined by \(f_{{{\text{decay}}}} = \exp (8.7044 \times 10^{{ - 4}} z_{{{\text{rcv}}}} )\), where zrec represents the depth of an in-air receiverBack to article page
