Measure your seismicity with SeismoStats, a Python package for seismicity analysis.

[!IMPORTANT]
We are happy to receive feedback and suggestions for improvement. Just open an issue here: https://github.com/swiss-seismological-service/SeismoStats/issues, and we will work on this as soon as possible.

Start using SeismoStats:

This is intended for people interested in using existing functionalities and functions in SeismoStats, for example if you want to calculate an Mc, a-value and b-value for your catalogue and plot the frequency magnitude distribution.

pip install seismostats

That's all, you can now use SeismoStats!

Installation from source

To get the very latest version of SeismoStats, you can install it directly from the source code. This is especially useful if you want to contribute to the development of SeismoStats.

After cloning, you can install SeismoStats by running the following command in the root directory of the repository:

pip install .

Or in development mode, including the development dependencies.

pip install -e '.[dev]'

To run the tests.

tox

We are actively working on a publication to submit with the first stable version of SeismoStats. If you use the code for scientific work, and until a pre-print is available, please cite SeismoStats as:
