Abstract

Seismic waves that observed in earthquake records are non-stationary typical. To better understand the structure of the seismic signals, not only is enough to examine changes at time domain, also frequency domain is shows a component characteristics of the signal important. Therefore in recent years, different time-frequency analysis methods are used extensively. Time-Frequency analysis is suitable for non- stationary signal analysis and processing. Time-frequency analysis contains a signal in both time domain and frequency domain at the same time. In this study we applied and compared a linear and a quadratic two different time-frequency analysis methods short-time Fourier transform and Wigner-Ville distribution in December 25, 2012 Georgia earthquake record. As a result of this study, short-time Fourier transform method gave better results than the Wigner-Ville distribution.
