HiBasin

The Hierarchical BAyesian Source INversion (HiBASIN) is a Python package to perform seismic moment tensor (MT), single force (SF), or joint MT and SF inversion within a hierarchical Bayesian framework incoporating uncertainty estimates for data noise and theory error. Hibsasin is based on MTUQ and emcee.

Installation

1. Requirements:

   • MTUQ (https://github.com/mtuqorg/mtuq)
   • emcee (https://github.com/dfm/emcee)
   • corner
   • pyrocko

2. Install HiBasin:

git clone git@github.com:mtuqorg/HiBasin.git
cd HiBasin
pip install -e .

Documentation

Read the MTUQ documentation for Acquiring seismic data, Acquiring Green's functions, and Data processing.
