SRAD radial diagram : a new way to display important aspects of fault-slip analysis results

Abstract EN

Aspects of stress inversion, such as angular deviation, stress ratio, orientation of the principal stress axes, and the normal and shear components of the resolved stress tensor on a fault plane, are given as output by many programs that address stress inversion.

However, comparison of results becomes difficult when the number of stress states and associated parameters increases.

A stress ratio-angular deviation radial diagram was constructed.

The diagram provides simultaneous illustration of the above parameters and facilitates the comparison and interpretation of up to eleven various stress states.

The application of the diagram is demonstrated by a worked example based on data obtained from the Tabriz North Fault in the Eastern Azerbaijan province NW of Iran.
