- Abstract
- Virtual source data were produced by applying the seismic interferometry to the 2002 experimental seismic refraction data. Using the data, moveout velocities and effective anellipticity were experimentally computed for the crust at eight sites in the Korean peninsula. The moveout velocities of reflection events at approximate Moho depths were yielded to be 6.30 +/- 0.25 km/s using near-offset traveltimes. Expanding the Taylor approximation to the 3 rd term for faroffset traveltimes, the effective anellipticity parameters were computed to be 0.18 +/- 0.07 for the crust material.
