Abstract：In order to determine the relative fixed positioning method of Shanxi station’s speed model based on the “Shanxi 2015 velocity model”, 103 earthquake events with the maximum clearance angle of less than 45° from 2010 to 2016 and more than 40 positioning stations are selected as targets. The results show that the residuals of the simplex method and Hyposat combined with PTD determination and the epicenter distance of the net margin earthquake are superior to that of Hypo2000 and of Hyposat binding PTD in terms of focal depth.According to the comprehensive analysis, when the Shanxi 2015 velocity model is used to locate the earthquake, the Shanxi network should be fixed with Hyposat and PTD method.
