Short summary
The goal of this study is to test the effect of incorporating rotational ground motion data into finite-source inversions for different types of earthquakes. We run numerical simulations with and without rotation data and directly compare the results. They clearly suggest that seismological studies can benefit from the ability of seismometers to also measure rotational ground motions, especially for faults which also fracture in vertical direction.
