| 摘 要： | Earthquakes taking place from 1975 to 2010 in and around Shandong Province are relocated using double-difference （HypoDD） and Hypoinvers 2000 （Hypo2000） methods, after correction of the onset times of seismic phases. The results show that the relocated seismicity is clearly associated with regional tectonics in space, and is also in agreement with the existence of deep faults imaged by wide-angle and deep seismic reflection profiling ; most of the focal depths are in the range of 5 - 25km, and there are clearly two predominant depths： 10km and 16km, which are inferred to be on the bottom of the upper crust and in the middle crust, respectively. The pattern of seismic activity indicates that moderate and strong earthquakes are likely to occur in the brittle-ductile transition zone between the upper and the lower crust, as the outcome of the deep tectonic dynamic process and the movement and deformation of faults in the upper and shallow crust under the regional stress field.
