Figure 1. Location map. Boxed area in inset shows location of Kunlun fault in northern Tibet. The red arrow in the inset indicates the relative motion of the Indian plate (Tapponnier et al., 2001). Box A indicates area A, which is a deformational setting characterized by strike slip with some transpressional component (Lin et al., 2003, 2004; Andronicos et al., 2004a, 2004b). Box B denotes area B, which lies in an area of transpression (Lin et al., 2003). Box C is area C and denotes an area of transtension (Lin et al., 2003, 2004; Andronicos et al., 2004a, 2004b). The dashed boxes represent rupture zone segments as defined by Lin et al. (2002, 2003). From left to right these segments are: Buka Daban Peak, Hongshui River, Kusai, and Kunlun Pass. Sites where offsets were measured by Lin et al. (2002, 2003) are shown by solid circles (see also Table 2). The colored line segments show the greatest compressional axes and represent the incremental strain field based on earthquake focal mechanisms (Andronicos et al., 2004a, 2004b). The focal mechanism plotted near Kusai Lake is from the Harvard Centroid Moment Tensor Catalog.

uncertainty in that measurement. Open circles represent slip measured in the field by Lin et al. (2003) where the fault strikes between 90.3° and 90.5°. Closed circles represent slip measured by Lin et al. (2003) where the fault strikes between 91.5° and 92.5°. Acronyms are as follows: BDP—Buka Daban Peak segment; HSR—Hongshui River segment; KS—Kusai segment; and KP—Kunlun Pass. Figure is modified from Lin et al. (2003).
