Fsa: Fault & Stress Analysis software

Purpose

1. faults, fault and slip, or earthquake focal mechanisms,
2. stress,
3. and the relationship between faults and the state of stress.

• Graphical representation of
  • Fault & slip: stereoplots, histograms, roses, Breddin's graph, trend and slip map
  • Stress tensor: stereoplots, histograms, roses, Frohlich's and Mohr's diagrams, Sh map
• Restoration of the orientation of tilted structures
• Stress tensor inversion from fault slip data
• Analysis of the state of stress on a fault

Documentation

• Documentation is (too) slowly being assembled in a user's manual that 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 the most recent MacOS X applications. It is still incomplete, but up do date. The 3 chapters on data files are intended to help prepare input files successfully.
  
• Older html documentation includes information on
  • data handled by Fsa
  • procedures included in Fsa
  • stress inversion set up and parameters
• The revision history and versions of the program are detailed in chapter 8 of the manual.
• How to refer to this program ?
  • If you publish results obtained with this program, it would be appreciated if you referred to it as indicated in chapter 7 of the manual.
  • Chapter 7 also gives references related to the methods implemented in the program.
