This paper presents a full waveform inversion of the kinematics of a simulated crack inside an artificial rock plate. A crack was simulated by a piezoelectric crystal embedded inside a gypsum plate, and excited by inputting an electrical signal. Elastic waves emitted from the simulated crack propagated through the plate and were recorded by an array of unique high-fidelity microseismic displacement sensors. This microseismic data is then inverted and the kinematics of the crack modeled by the moment tensor, which can be obtained by deconvolving the recorded signals with the dynamic Green's functions. Green's functions were calculated based on two different models: The first model assumes elastic, homogeneous, and isotropic conditions while the second model assumes anelasticity. The effect of using these two models on the estimated kinematics of the simulated crack was then investigated. The two models result in different Green's functions with a variation of 70≤Q_p≤190 having little effect on the damped result.
