Abstract:

Long period signals and noise recorded at the seismic arrays UBO, TFO and LASA were analyzed to provide information useful to signal detection efforts and to evaluate the performance of simple long-period beams formed with these arrays. The analysis included the computation of group velocity dispersion for fundamental mode Rayleigh waves generated by seismic events recorded at these arrays, and the calculation of noise reducing properties of beamforming each of the three arrays for a set of twenty five events.
