QuakeMigrate
QuakeMigrate
is a Python package for automatic earthquake detection and location using waveform migration and stacking.
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, a catalogue 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
The source code for the project is hosted on GitHub.
