Extensional Seismotectonic Motion and its Dynamics in the Eastern Margin of the Tibetan Plateau and its Surroundings
Author(s): Jiren Xu and Zhixin ZhaoJiren Xu and Zhixin Zhao
The seismotectonic motions and stress fields in the eastern margin of the Tibetan plateau and its surroundings were investigated by analyzing seismic data. The findings showed that volumes of normal faulting type events dislocating extensively along the N-S direction concentrated southwest of the Xianshuihe fault (SWXSH-NSNF). Moreover, volumes of normal faulting type events dislocating extensively along the E-W direction concentrated east of the lower reach of the Jinshajiang river (ELRJSJ-EWNF). The events are almost thrust faulting type ones along the Longmenshan fault. The P-axes aligned generally around the NE-SW direction in the western region and around the NW-SE direction in the eastern region in the eastern margin of the plateau, respectively. The seismogenic stress field in the eastern region in the eastern margin of the Tibetan plateau might be affected by the stress field .. View More»
