In this paper,18 explosion tests from 2010 to 2012 of the project of Fujian and the Taiwan Strait Deep Crustal Structure Sea Joint Exploration are used to obtain explosion times and explosion locations so as to determine multiple phase travel time. First we analyze the characteristics of blasting vibration,make a comparison of four location methods of Simple,Hyposat,Hypo2000 and Locsatin for the Southern China model to get the optimal location method. We use the model obtained from the blasting records of 14 inversion results and compare with the Southern China model. The results show that the upper crust thickness is smaller than that of the Southern China model,and the lower crust thickness is greater than that of the Southern China model. The velocity of the upper crust is equal to that of the Southern China model and the velocity of the lower crust is faster than that of the Southern China model. The remaining four blasting records are applied to locate in this inversion model. It is concluded that the location accuracy has improved significantly.
