Statistical evaluation of CTBT regional seismic monitoring

摘要

A global seismic monitoring system under a Comprehensive Test Ban Treaty (CTBT) is judged by its capability to detect, locate, and identify suspicious seismic events. Performance measures are those statistical objects that describe these capabilities. Performance criteria are the thresholds derived from the overall monitoring system goals, against which the evaluated performance measures are compared. This report proposes statistical objects for performance measurement of detection and location, a continuation of the research of Anderson and Anderson. A statistical methodology for calibrating regional station magnitudes to the worldwide teleseismic Mb scale is also proposed.
