13.1 Introduction

In a high signal-to-noise environment, a single triaxial geophone can provide estimates of the polarization state of a seismic arrival. Knowledge of the mode of the event (e.g., P-wave) and elastic properties of the host rock can be used to infer the direction of propagation. Alternatively, knowledge of the direction of propagation can be combined with the polarization state to identify the various wave modes and characterize the elastic properties of the host rock. Polarization analysis might, for example, allow body waves (rectilinear polarization) to be distinguished from surface waves (elliptical polarization). Polarization measurements are therefore important in many areas of seismology.
