Extended Array Evaluation of the Noise Characteristics and the Detection and Discrimination Capabilities of the Very Long Period Experiment (VLPE) Single Stations and the VLPE Network
Abstract
The report presents an evaluation of the noise characteristics of eight VLPE stations, the detection and discrimination capabilities of eleven VLPE stations, and the VLPE network. Spatial and temporal noise relationships are presented for eight VLPE stations. Maximum likelihood m sub b detection estimates show for the 50% detection threshold at single stations an m sub b of about 4.7 and for the VLPE network an m sub b of about 4.2 Matched filters applied to a selected suite of events increases the number of detections by a factor of two. The discrimination capability of the single VLPE stations and the VLPE network is presented in terms of M sub s versus m sub b, Love to Rayleigh wave amplitude ratios, and surface wave radiation patterns.
