Build Status codecov Documentation Status Binder

QuakeMigrate is a Python package for automatic earthquake detection and location using waveform migration and stacking. It can be used to produce catalogues of earthquakes, including hypocentres, 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.

Installation

Installation instructions can be found here.

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.

Binder

To quickly get a taste for how the software works, try out the two icequake examples hosted on Binder:

  • Icequakes at the Rutford Ice Stream, Antarctica badge
  • Icequakes at the Skeiðarárjökull outlet glacier, Iceland badge

And for a more comprehensive demonstration of the options available, see the template scripts.
