Title

Comparison of surface wave tomography results using the first order Tikhonov regularization and Yanovskaya-Ditmar (1990) method

Pages

Abstract

 Summary Two-dimensional (2-D) Surface wave tomography is one of the most practical approach to reveal the lateral variation of phase/group velocity. Hence, various methods have been introduced to attain the more accurate images. In this paper, we compare two different tomography methods (Tikhonov regularization method and Yanovskaya-Ditmar method) and try to show their advantages and drawbacks resulted from their basic assumptions. We first investigate the lateral resolution capability of the methods using the synthetic checkerboard test in cases of Noise free and Noise level of 3%. Synthetic models are considered with different grid spacings of 0. 5˚ ×0. 5˚ , 1˚ ×1˚ and 2˚ ×2˚ . Then, they were applied on real data containing Phase velocity obtained from the teleseismic Rayleigh waves recorded at broad band stations located in Iran at the period of 30 s. A comparison of the results obtained from the Tikhonov regularization and Yanoskaya-Ditmar methods shows that the former method has a better lateral resolution than the latter method...
