Utilizing Rotational Data for Seismic Polarization Analysis and Filtering of Vertical Component Data

Field data recorded by a new rotational 6-degree-of-freedom sensor have been analysed. Rotational components were used for evaluating the polarization vector of the seismic events in the data and a polarization-based filter was designed to reject rotational data from vertical component data in chosen directions. The polarization approach shows positive results when applied to field data but also indicates the need for some improvements.
