von Seggern, D H; Sobel, P A

Seismic discrimination in the Kamchatka source region is studied using data from earthquakes, inferences from measurements of teleseismic explosions, and results from the Amchitka tests. On the basis of several parameters taken together, such as M sub s - m sub b, spectral ratio, corner frequency, complexity, long-period body-wave excitation, and shear-wave excitation, discrimination of events of this type in the Kamchatka region poses no special problems so long as discrimination against shot arrays is not at issue. If shot arrays are considered, then the problem is more difficult, but still tractable.
