Abstract

Seismic interferometry is applied for F-net contentious data in western Japan area to obtain Green's function between station-pairs for validating crustal velocity structure model. As part 1, we estimated observed Green's functions and see the characteristics. 1) Signals of the observed Green's function have sufficient SN ratio for 2-15 s with station distances up to 250 km. 2) The signals mainly composed by surface waves that were judged by particle motion and group velocity characteristics. 3) The observed Green's functions show seasonal variation.
