A high intensity of crustal movement around Shenzhen City area is shown by various determining methods

such as the amplitude and velocity of the differential uplifting and subsiding of the fault blocks

the hydro-thermal activities. the distributions of the block’s stress and the activities of faults and seismicity sin Late Tertiary

especially since Holocene.The fault zone does not provide the geological background of occuring macroseisms. The evaluation of the regional stability in Shenzhen Fault-block area shows that Shenzhen City belongs to a stable area. Though the facts that Shennzhes City is just located in the Shenzhen Fault Zone and the basement in Shenzhen is very scattered increase the investment and the working time

the fault zone had undergone a long time of erosion and formed a broad alluvial plain where has become sites for engineering constructions. After studying the Shenzhen Fault Zone

it is believed that its activity is weak and the possibility of causing great earthquakes is minor. As long as we pay enough attention to it

take corresponding treatment and strengthen the tacklings of the basement

we can ensure the safety of the city. In order to monitor the activities in different parts of Shenzhen Fault Zone

it is recommended that land deformation geodetic measurement

including leveling and triangulation should be carried on. and some datings of the active faults should be done.
