Abstract:The present horizontal movement characteristics of the Ordos block is the result of the interaction between the Ordos block movement itself and the whole movement of the mainland of China. The power source of Ordos block is mainly by push from the Qinghai-Tibet block from a NE direction, and the NW extension of the northern margin of the block. The latest GPS velocity field observational evidence from 1999 to 2015 shows that the resultant changeis significant. The velocity field change is more significant in the northeast, northwest, southwest and southeast margins of the block; the left lateral movement speed of the north and south margin is much larger than the right lateral movement speed of the east and the south marginsof the Ordos block. Seismic activity, strain accumulation and release, stress distribution and stress field analysis using the present seismic data since 1970,show that the northern margin of the Ordos block is the main region of strong earthquake activity; this is not only at the block edge, but also in north China. The energy around the Ordos block has accumulated continuously since 2000.This is the longest period since 1970, until the Alashanzuoqi 5.8 earthquake in 2015. The periphery of the block has shown signs of pre-release energy, and there is an abnormal area of stress distribution in the north margin of the Ordos block.
