| Abstract: | As the classical time or frequency Fourier analysis alone are insufficient to provide comprehensive information about the seismic signals who are known to be nonstationary, of ondulatory type and with time-frequency dependent energy power distribution, the more complex bi-dimensional time-frequency analysis methods are necessary to be employed. The studies of the seismic signal using time-frequency analysis are scarce. The authors’ main goal is to evaluate the effectiveness of those methods relatively to Vrancea Fault generated earthquakes. The paper, for editorial space reasons, provides just a very brief description of the theoretical and numerical results of the time-frequency analysis conducted on 13 recorded strong ground motions generated by the Vrancea Fault. |
