HypoInvPy

*A Python interface for HypoInverse earthquake relocation software

This package is not intended to show documentation of how to use hypoinverse. Instead, we focus on buiding an user-friendly Python interface to run hypoinverse. For detailed documentation of hypoinverse, please read the documentation for hypoinverse in hyp1.40/doc/hyp1.40.pdf. The documentation for this interface package is in doc/HypoInvPy_manual.pdf.

Credit note

The codes and workflow in this package are modified and simplified from Hypo-Interface-Py (https://github.com/YijianZhou/Hypo-Interface-Py). The hypoinverse version is 1.4 and can be downloaded from USGS (https://www.usgs.gov/software/hypoinverse-earthquake-location).

Installation

1. Create and activate a Python virtual environment hypoinv. This is optional but recommended. This will help isolate the computational needs from other packages. This will also help avoid version incompatibility in case new packages for some codes are updated in the base conda environment. However, since HypoInvPy doesn't currently need complicated packages, running under the base environment may just work fine.

$ conda create -n hypoinv -c conda-forge jupyter numpy scipy pandas python cartopy obspy mpi4py

Then, activate the environment with: $ conda activate hypoinv

2. Install the package with the parameters in setup.py.

$ pip install .

3. Create jupyter notebook kernel with the environment (after activating the environment).

$ pip install --user ipykernel
$ python -m ipykernel install --user --name=hypoinv

Run the hypoinverse example:

1. Make sure hypo1.40 has been installed on your computer. Download the version from the USGS website (https://www.usgs.gov/software/hypoinverse-earthquake-location). For your convinience, a copy of the hyp1.40 codes is available under folder hyp1.40.
2. In terminal under the package directory, type: python run_hypo.py
3. The output directory includes the resultant earthquake catalogs.

The run_hypo.py script already includes steps to reformat the phase and station information.

Upcoming changes:

• Incorporate the functionality into a standalone python package.
• Change mk_pha.py and mk_sta.py into functions.
• Embed the template parameters into functions.
• Add utility functions to convert data formats.
• Add visualization functionalities, e.g., earthquake locations and depth distribution and temporal sequence, etc.
