It might be a high-priority task for you, it might be for all of mankind and our planet too. But for us to understand that you have to explain why, is an earthquake coming that we somehow can prevent? Some other vibration-related disaster?

Have a look at the spectrogram function, it should give you the signal spectra. If you really just want the fft, why not look at the fft function?
