Figure 5.8 Joint inversion of the seismic and electrical waveforms. Application of the MCMC samplers to determine the posterior
probability density of the seven model parameters (including the source location, the thickness of the first layer, the seismic magnitude,
and the three components of the moment tensor). Each dot corresponds to one realization of the MCMC sampler. The solid horizontal
lines correspond to the true values of the model parameters.

Figure 5.9 Posterior probability density function of the seven model parameters computed from the noise-free seismic and electrical
data. The model parameters include the source location ( x s , z s ), the thickness of the first layer h d , the seismic magnitude M w , and the
three moment tensor components ( M xx , M xz , M zz ). The solid vertical bars indicate the true value of the model parameters. The
information content of the seismic and electrical data is the same.
