Abstract:

A preliminary evaluation of the Korean Seismological Research Station Short-Period Array is presented in this report. Six noise samples from November 1974 were analyzed yielding spectral content, noise amplitudes, multiple coherence, frequency-wavenumber spectra, and noise reduction due to beamforming. Analysis of eight Eurasian teleseismic events from November 1974 included measurements of single-sensor similarity and amplitude variations across the array. In the beamforming studies, time-delay anomalies, spectral content, frequency-wavenumber spectra, signal degradation, signal-to-noise improvements using beams, and m sub b estimates were calculated. A preliminary estimation of the detectability of Eurasian events was also made.
