The Evolution of Stress and Strain around the Bayan Har Block in the Tibetan Plateau

Figure 1

Tectonic setting and distribution of recent large earthquakes around Bayan Har block. Mechanisms of earthquakes come from Harvard CMT catalogue (http://www.globalcmt.org/CMTsearch.html). The blue arrows show the movement of block in the Tibetan Plateau according to GPS observation. Red solid lines indicate the major active faults around Bayan Har block [3, 12, 43]. F1: Heishibeihu fault; F2: the middle segment of East Kunlun fault; F3: eastern segment of East Kunlun fault (Maqu-Heye segment); F4: Longmen Shan fault; F5: Yushu-Xianshuihe-Anninghe fault; F6: Margaichaka-RolaKangri faults. The black dashed lines show the boundary of different block in the Tibetan Plateau. The red dashed lines show the area of the finite element model (Figure 2).
