| Abstract: | The observational data from the seismic station network of Liaoning province were processed by using a new method of seismic velocity imaging and computer program. It gives new results of the three dimensional crustal structure of the Haicheng seismic area and neighboring regions. The analyses confirm again that the crustal structure on the borth sides of the Haicheng seismic area is rather different. The focuses of Haicheng earthquakes are located above a NWW trending low velocity body in the crust. |
