Monitoring Velocity Changes using Ambient Seismic Noise

SeisMIC (Seismological Monitoring using Interferometric Concepts) is a python software that emerged from the miic library. SeisMIC provides functionality to apply some concepts of seismic interferometry to different data of elastic waves. Its main use case is the monitoring of temporal changes in a mediums Green's Function (i.e., monitoring of temporal velocity changes).

SeisMIC will handle the whole workflow to create velocity-change time-series including:

• Downloading raw data
• Adaptable preprocessing of the waveform data
• Computating cross- and/or autocorrelations
• Plotting tools for correlations
• Database management of ambient seismic noise correlations
• Adaptable postprocessing of correlations
• Computation of velocity change (dv/v) time series
• Postprocessing of dv/v time series
• Plotting of dv/v time-series
• Inverting dv/v onto a spatial grid

SeisMIC handles correlations and data in an ObsPy-like manner.

Installation of this package

Installation from PyPi (pip install)

SeisMIC is now deployed on PyPi and can simply be installed using:

# We recommend installing mpi4py from the conda-forge channel instead of PyPi
conda install -c conda-forge mpi4py

pip install seismic

# If you want to execute the tutorials, you will have to install jupyter as well
pip install jupyter

Installation from Source Code

To obtain the lates features, you can install SeisMIC from its source code, available on GitHub.

Developers should download the dev branch

Download this package via GitHub and install it via bash terminal (the few steps shown below) or using the graphical user interface

# Download via wget or web-browser
wget https://github.com/PeterMakus/SeisMIC/archive/refs/heads/main.zip
