For simplicity, I will refer in this section to the fundamental (1st) mode defined by the circular frequency ω0 = 2πf0. WebThe Rayleigh wave characteristics have been separated from the velocity records using the method of time–frequency decomposition. Finally, a collected database of 6-DoF records was used for determining the relation between the rotational ground movement, seismic energy and vibration frequency of the tremor. 2.
