Abstract：An improved method is proposed for picking up seismic first arrivals in this paper, The basic principles of"division method"are used to calculate the fractal dimension along setsmtc traces.and pick up the first arrivals from its changing characters.However,the formal algrithrn is time-consuming and the results rely on the accuracy of interpolation.The algorithm proposed in this paper avoids interpolation in calculating procedure,so that improves calculaspeed and strengthens stability of calculation results.
