Extended Array Evaluation Program. Special Report No. 8. Preliminary Network Evaluation Studies
Abstract
Theoretical single-station and network signal detection capability models for surface waves are given in this report. Application of these models to world-wide signal detection capability by the Very Long Period Experiment stations and the ALPA, NORSAR, LASA arrays show high probability of at least 2- station detection at about Ms = 3.0 - 3.1 for most of Eurasia for both 20 and 40-second Rayleigh waves. More rapid attenuation of the 40 second wave amplitudes with distance compared to 20 second amplitudes is demonstrated and included in the theoretical capability model. Evaluation of a network of such stations to decrease problems in detection, unmixing of signals, and evaluating source radiation pattern effects is discussed.
