///There are two earthquakes in Gaize on Jan 9 (Ms 6.9) and Jan 16,2008 (Ms 6.0).The two earthquakes were selected as examples to obtain the co-seismic deformation field with the 2-pass differential interferometric processing method. The results show that the earthquake faults locate near the tip of the Yibuchaka-Riganpeicuo Fault, and both seismic faults are normal faults; The seismogenic fault of the main shock strikes about N30°E and that of the aftershock strikes about N21°E. There is evidence of surface rupture along the mainshock’s causative fault, but no surface rupture has been observed on the aftershock fault. The co-seismic deformation field is about 30 km in length and 20 km in width; The maximum displacement in LOS of the hanging wall of the main-shock fault is 39.2 cm, and that of footwall is 11.2 cm,the relative dislocation between them is 50.4 cm. The displacement caused by the aftershock is 9.4 cm (LOS).
