Abstract: The machanical nature of faulting and its classification and its names given were dealt with under consideration of rakes/dips for the nodal planes and relative motion of the blocks by use of mechanism solution of the earthquakes in China.The faulting is named by combining its three factors,the type of slip,relative motionn of blocks and dip angle.Some main characteristics of the faulting in China were discussed briefly in the end of the paper.
