Abstract:The lack of the suitable velocity model for the Shanxi seismic network led the present study on one dimensional crustal velocity model in Shanxi. Based on the collection of the previous work,which includes a large number of seismic phase data produced by the Shanxi seismic network during the period of 2009-2014. The fluctuation range of velocity and depth in the model parameters were determined by the method of linear fitting and "reduced travel time". Then 76 seismic events were batch located by using Hyposat location program and 46,489 sets of models. A set of parameters with minimal residual error was picked up as a new model. Finally,the Shanxi 2015 velocity model was verified through 3 different ways:the comparison of the residual error of the batch location,PTD measured depth and the artificial blasting. The results showed that the 2015 Shanxi crustal velocity model has less residual error,higher accuracy and better applicability thhan thhe modified J-B model which is being used now for the earthquake location in Shanxi.
