1 We have detected detailed ground displacements in the proximity of the 2 Longmen Shan fault zone (LMSFZ) by applying a SAR offset-tracking method in the 3 analysis of the 2008 Sichuan earthquake. An elevation-dependent correction is 4 indispensable for achieving sub-meter accuracy. A sharp displacement discontinuity 5 with a relative motion of ~1-2 m appears over a length of 200 km along the LMSFZ, 6 which demonstrates that the main rupture has proceeded on the Beichuan fault (BF) 7 among several active faults composing the LMSFZ, and a new active fault is detected 8 on the northeastward extension of the BF. The rupture on the BF is characterized by a 9 right-lateral motion in the northeast, while in the southwest an oblique right-lateral 10 thrust slip is suggested. In contrast to the northeast, where a major rupture proceeded on 11 the BF only, in the southwest multiple thrust ruptures have occurred in the southeastern 12 foot of the Pengguan massif. 13
