摘要：
The deep structure features around Tancheng M8（1/2）earthquake occurred in 1668 have been analyzed. Based on the crustal velocity structure obtained from travel-time tomographic inversion,especially the low velocity zones in middle crust and Moho depths,the deep velocity structure distribution in the area of 34° ~ 36°N,118° ~ 119°E is scanned along the latitude,longitude and oblique directions,and the corresponding crustal velocity profiles are obtained. By comparison,we take the area with velocity features coincident to the deep structure of the 1668 Tancheng M8（1/2） earthquake as the deduced epicenter,which is at 34. 8° ~ 35. 2°N,118. 2° ~ 118. 7°E,and the reasonable location is 35. 1°N,118. 6°E,and the focal depth is 20 km.
