| Abstract: | Based on the focal depth, focal mechanism of earthquakes in the northeast of Qinghai-Xizang Plateau and the movement features of the faults in the surrounding area since Late Epipleistocene, this paper discussed both the main characteristics of the block movement of upper crust in this area, and the phenomena and the causation of the geomorphological retardation effects in the active tectonic zone along the north edge of West Qinghai mountain, as well as the causation and the zonation of strong earthquakes generated in the area somewhat like a sluice gate. |
