| A Stress Inversion Procedure for Automatic Recognition of Polyphase Fault/Slip Data Sets |
| The presence of polyphase fault/slip data caused by the variability of tectonic stress fields in the geological history is a general problem in stress inversion. Algorithms previously presented for separation of polyphase fault/slip data sets are based on hard subdivision and underestimate the intrinsic nondeterminacy of data. In some of these algorithms, the classic algorithm for one phase fault/slip data is embedded. In Fry's (1999) sigma space, the vectors of one phase fault/slip data must have a linear tendency whe reas the vectors of polyphase data have multiple linear tendencies. The authors herein apply modern fuzzy clustering analysis to detec ting the linear structures of fault/slip data. The algorithm used here considers the nondeterminacy of data and hence can overcome the shortcomings of existing algorithms. It is automatic, direct and effective,and needs less running time. |
