Abstract:

The performance of two seismic event detectors, the Fisher detector and the conventional power detector, was compared. Long-period records with low signal-to-noise ratios, recorded at the Alaskan Long Period Array, were used to establish performance characteristics, sensitivities, response to off-azimuth events, and response to signal distortion. Results confirmed the theoretical prediction that there is no important distinction between the detectors.
