Abstract:

A matched filter approach for distinguishing weak teleseismic surface wave signals from background noise is presented. The method discriminates against events not located in a particular source region of interest and provides estimates of magnitude and radiation pattern, when a number of recording stations are available. Test cases and typical results for different source regions are discussed.
