| 英文摘要 | The nov. 8, 1997 mani (xizang) mw7.5 earthquake is an important event since synthetic aperture radar interferometry was used for earthquake studies. in the first part we use the widely-used okada linear elastic dislocation model and assume uniform slip on fault segments to invert the geometric parameters and the uniform slip. in this part we remove the uniform slip assumption, use more realistic angular dislocation model (linear elastic) to invert the static slip distribution on fault. the inversion result shows that this linear elastic slip distribution can explain the data better, and the goodness of fitting is improved further. we get both of the strike-slip distribution and the dip-slip distribution on the fault plane. the first-time acquired slip distribution indicates that the fault slip concentrates mainly in the shallow depth (0 similar to 12 km), the earthquake rupture is 170-km-long, the maximum left-lateral strike-slip is 4.8 m; the inversion result also shows that there are large dip-slip on some segments and their magnitude reaches 1.9 m, which can't be ignored in the inversion. the dip-slip may be one of the reasons of the asymmetric deformation pattern beside the two sides of the fault; the inverted seismic moment is 2.18 x 10(20) n center dot m, equal to magnitude mw7.5. it's consistent with the seismic waveform inversion of velasco. |
