Python package for focal mechanism stress inversions

pySATSI

Python package for focal mechanism stress inversions.

Author: Robert Skoumal, U.S. Geological Survey | [e-mail]

This project contains Python code to compute damped stress inversions using earthquake focal mechanism solutions.

How to Use

1. Install the latest release in your virtual environment:

# If you don't want to create any plots:
pip install -U pySATSI

# If you do want to create plots:
pip install -U 'pySATSI[plot]'

Python 3.8+ versions are supported.

2. Run pySATSI with your desired control file:

pySATSI path_to/control_file.txt
