Abstract:

Polarization filters, designed to detect rectilinear orbital motion recorded on 3-component seismograms, were applied as aids in the detection and identification of the phases pP and sP from eight large teleseismic earthquakes. The filters were designed to pass the frequency bands corresponding to any motion which is at least moderately rectilinear along any direction within a vertical quadrant from which the phases were expected to arrive. Experimental filters of higher selectivity, more appropriate to detecting weak signals in signal-generated noise, were demonstrated in a few examples. Author
