摘要: Averages of P - and S -wave radiation patterns over all azimuths various ranges takeoff angles (corresponding to observations at teleseismic, regional, near distances) have been computed for use in seismological applications requiring average coefficients. Various fault orientations averages the squared, absolute, logarithmic considered. Effective combining high-frequency direct surfacere-flected waves from shallow faults also derived used computation coefficients teleseismic distances. In most cases, are within a factor 1.6 commonly values 0.52 0.63 rms patterns, respectively, averaged whole focal sphere. The main exceptions this conclusion distances vertical strike-slip faults, which least 2.8 smaller than value.
