Extraction of Long-Period Bodywaves
Abstract
A polarization filter for long-period bodywaves was developed and tested on 100 events from the Kurile Islands and measured at the Guam Seismic Research Observatory. Fifty percent detection thresholds before processing were m sub b = 5.5 and 5.1 for P and S waves, respectively, and were unchanged by the filter unless a substantial false alarm rate was allowed, when the P threshold was reduced to m sub b = 5.0. There is evidence that this poor performance is due to the data set used.
