Center for Seismic Studies Final Technical Report, October 1992 through October 1993

Abstract

A 1992 study by Suteau-Henson where azimuth bias and scatter were systematically measured for regional phases of events recorded at ARCESS is extended here by mapping the observed bias and scatter around ARCESS. In another study, the optimization of polarization analysis at IMS/IRIS stations in the Former Soviet Union is addressed. Also in this report, a procedure to stack waveforms recorded by a network of seismic stations for detection of depth phases, sP and pP is defined. The constraint on focal depth provided by origin times determined from travel time ratios of P and S waves is also studied. Finally, we perform some computational experiments to outline the depth estimation capability of the GSETT-2 global network and a hypothetical network consisting primarily of high sensitive array stations. Scatter, Waveforms, GSETT-2, ARCESS, Depth phases, Polarization analysis, Focal depth.
