Sukarapi fault stereographic analysis
The stereographic solution translates the Sukarapi measurements into a three-dimensional kinematic hypothesis, but the input notation and projection conventions must be auditable. Plane strike/dip, slickenline rake or trend/plunge, lower- versus upper-hemisphere projection and assumed movement sense should be listed explicitly.

Geological interpretation and evidential boundary
The stereographic solution translates the Sukarapi measurements into a three-dimensional kinematic hypothesis, but the input notation and projection conventions must be auditable. Plane strike/dip, slickenline rake or trend/plunge, lower- versus upper-hemisphere projection and assumed movement sense should be listed explicitly. Calling a fault ‘vertical strike-slip’ is inconsistent with a reported dip near 62° unless the term is used broadly; oblique-slip should be considered if the lineation has a substantial dip component. Uncertainty should include measurement dispersion and alternative nodal solutions. The stereonet is valuable as a consistency test between field geometry and regional structure, not as a substitute for shear-sense evidence.
