Particle Man

Particle motion analysis of seismic surface waves using the Stockwell Transform.

• Documentation

Seismic surface waves can be detected and extracted from three-component data through particle motion polarization analysis. Particle Man is a software package that employs the Stockwell Transform to perform surface wave filtering/extraction and display for multifrequency analysis.

This package implements the Normalized Inner Product surface wave filtering and extraction methods of Meza-Fajardo et al., (2015). The Stockwell transform is implemented in C using FFTW libraries.

Installation

Prerequisites

• C compiler
• fftw3

Dependencies

• Python 3
• NumPy
• Matplotlib

Using from a Conda environment.yml

The environment.yml file will install everything you need into a particleman environment: conda env create -f environment.yml. To install Particle Man into an existing Conda environment, make sure you've got the dependencies you need installed and available, and just use pip to install it from source.

Manually on a Mac

gcc from XCode should work fine. Getting fttw3 is easy with homebrew (brew install fftw) or with Conda (conda install -c conda-forge fftw).

To Particle Man install from source, just:

pip install .
