Based on the method of using a number of seismic activity parameters to determine activity features of fault zone segments,current seismic activity and seismic risk features of different segments of Cenozoic tectonic deformation zones in Anhui Province are analyzed.

By means of the characteristic analysis on geometry, kinematics and dynamics of the crenulation cleavage in Dalangshan area, this paper reveals that the crenulation cleavage is the basis of the formation and development of three large scale NW -trend brittle -- ductile shear zones from indosinian epoch to Yanshanian ePOch.
