Extended Array Evaluation Program. Special Report No. 13. Evaluation of the Discrimination Capability of the Norwegian Seismic Array

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 b)((M sub s)- (m sub b), AR/(m sub b)); Love wave energy versus (m sub b)((M sub s)-(m sub b), AL/(m 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.
