STRESSINVERSE Software for Stress Inversion

Abstract
The STRESSINVERSE code uses an iterative method to find the nodal planes most consistent with the stress field given fault frictional properties. STRESINVERSE inverts the strike, rake and dip from moment tensor solutions for the in-situ state of stress. The code iteratively solves for an optimal friction parameter in evaluating the fault instability to find optimal fault planes. Vavrycuk (2014) states that numerical tests show that inversion results are insensitive to the friction parameter, and it is sufficient to assign a reasonable value for all inversions.
