Abstract:

The report presents results from an evaluation of the discrimination capability of the Norwegian Short and Long Period Array NORSAR for Eurasian events. The following types of discriminants have been analyzed and their performance has been compared Rayleigh wave energy versus m sub bM sub s- m sub b, ARm sub b Love wave energy versus m sub bM sub s-m sub b, ALm sub b short period P-wave complexity versus m sub b three discriminants and short period P-wave spectral content versus m sub b dominant period, spectral ratios. The total data base for this evaluation consists of 233 earthquakes from 1971-1972 and 24 presumed explosions from 1971, 1972, and 1973.
