Fsa: Fault & Stress Analysis software

Purpose

1. faults, fault and slip, or earthquake focal mechanisms:
• graphics: stereoplots, histograms, roses, rake versus strike plots (to be overlain by Breddin's graph), trend and slip map;
• restoration of the orientation of tilted structures;
2. stress:
• graphics: stereoplots, histograms, roses, Mohr's diagrams, Frohlich's triangular representation, tectonic regime diagram, Sh map;
3. and the relationship between faults and the state of stress.
• Stress tensor inversion from fault slip data
• Analysis of the state of stress on a fault

Documentation

• A user's manual folder contains a pdf document and associated files. To keep its links active, it is recommended to preserve its folder structure after downloading. It is bundled with recent applications. It contains all that is needed to prepare input files.
• Chapter 13 of the manual gives suggestions on how to refer to Fsa and references pertaining to the methods implemented in it.
