Some Notes on Long-Period Signals

Abstract

The problem investigated was the one of long-period signals (30-60 seconds) from a single three-component seismometer to determine the Love and Rayleigh components of an explosive event in the presence of noise or an interfering earthquake. A review of current knowledge concerning long-period noise characteristics and interfering earthquake signals is made. In addition, a review of work concerning experimental studies of ellipticity is made.
