However, non-DC source components are sensitive to event mislocations and inexact velocity models of the crust. Inaccuracies such as these can generate spurious non-DC components in the mechanism, which should be taken into account during the interpretation. We perform a synthetic case study simulating seismic observations at Soultz-sous-Forêts, Alsace, hot dry rock (HDR) site. Synthetic P and S amplitudes for several shear-tensile source models are inverted, assuming hypocenter mislocation and velocity structure mismodeling in several types of station coverage.
