| Abstract: | According to the earthquake sequence after Wenchuan earthquake occurred on May 12, in 2008, we chose several groups of earthquakes as source arrays by the correlation character of the events. Naqu seismic array in Xizang Autonomous Region and Hetian seismic array in Xinjiang Uygur Autonomous Region were the receiver seismic arrays to be chosen. The array response functions were calculated for both receiver arrays and source arrays, and the transfer function equivalents for the double-beam configurations were also calculated. The results show that wenchuan earthquake sequence could form source arrays and these cheap arrays could be researched by the using of special array seismology methods. The transfer function equivalents for the double-beam configurations have higher resolutions in slowness field than the receiver arrays, which indicate the capability to disclose the smaller structure of the interior of the earth. |
