FOURIER SPECTRA OF SEISMIC WAVES GENERATED BY VRANCEA FOCI
(Abstract)
The Fourier spectra for 15 Vrancea microearthquakes are calculated.
According to their shape, the spectra can be classified into four types which
are supposed to depend on the depth and focal mechanism.
The predominant period shows a characteristic jump at (S – P) = 9 s.
