| 英文摘要 | Regional seismic waveforms are very useful for investigating earthquake source. However, partial near-field seismic data of Regional Seismic Network are clipped. Therefore, it could not be applied to determine the accurate source parameters directly. In this paper, the magnitude, source mechanism and rupture process of M(W)6. 6 Lushan earthquake were studied based on the restored regional seismic waveforms. The magnitude changed from 7. 01 to 7. 06 based on clipped and restored surface waves of stations with epicentral distances from 99km to 300 km. Clipped and restored regional waveforms of 7 stations with epicentral distance 150 km to 250 km are utilized to get the source mechanism respectively. Compared to the reference mechanism solution, the misfit of rake angle is reduced from 13 degrees to 4 degrees. Based on 7 regional seismic waveforms with epicentral distance from 81 km to 134 km combined with teleseismic data, the main parameters (such as slip distribution, rupture velocity, etc.) of the rupture process are similar to that of the result constrained by local strong motion data and teleseismic waveforms. These studies verify that this method is reliable and can play an important role in the earthquake source research. |
