<a href="https://quakemigrate.readthedocs.io/en/latest">QuakeMigrate</a> is a Python package for automatic earthquake detection and location using waveform migration and stacking.</a>

Key Features
------------
QuakeMigrate uses a waveform migration and stacking algorithm to search for coherent seismic phase arrivals across a network of instruments. It produces—from raw data—catalogues of earthquakes with locations, origin times, phase arrival picks, and local magnitude estimates, as well as rigorous estimates of the associated uncertainties.

The package has been built with a modular architecture, providing the potential for extension and adaptation at numerous entry points. This includes, but is not limited to:
* the calculation or import of traveltime grids
* the choice of algorithm used to identify phase arrivals (for example by kurtosis, cross-covariance analysis between multiple components, machine learning techniques and more)
* the stacking function used to combine onset functions
* the algorithm used to perform phase picking

Documentation
-------------
Documentation for QuakeMigrate is hosted [here](https://quakemigrate.readthedocs.io/en/latest/index.html).

Installation
------------
Detailed installation instructions can be found [here](https://quakemigrate.readthedocs.io/en/latest/installation.html).

If you're comfortable with virtual environments and just want to get started, QuakeMigrate is available via the Python Package Index, and can be installed via pip:

```console
pip install quakemigrate
```

Usage
-----
We are working on tutorials covering how each individual aspect of the package works, as well as example use cases where we provide substantive reasoning for the parameter choices used. These examples include applications to cryoseismicity and volcano seismology.

This is a work in progress - [see our documentation for full details](https://quakemigrate.readthedocs.io/en/latest/tutorials.html).

For a demonstration of the options available, and a starting point to write scripts for your own use-case, see the [template scripts](examples/template_scripts).
