BackTrackBB is a program for detection and space-time location of seismic sources based on multi-scale, frequency-selective statistical coherence of the wave field recorded by dense large-scale seismic networks and local antennas. The method is designed to enhance coherence of the signal statistical features across the array of sensors and consists of three steps:

• signal processing;
• space-time imaging;
• detection and location.

Clone or download the project from GitHub, if needed uncompress the archive.

Note: You will need a C compiler (ex., gcc or clang).

Run the following command from within the main directory:

pip install .

or to install developer mode use:

pip install -e .

You can use the above instructions for Linux and macOS, if you have a recent version of Visual Studio.

Alternatively, download the most recent Windows build of backtrackbb from this link (python wheel file) and install it with:

pip install backtrackbb-VERSION.whl

where VERSION is the current backtrackbb version string (part of the file name).

First, download the file examples.zip containing additional data (seismograms and theoretical travel-time grids).

Run the main detection and location code on an example dataset:

btbb  examples/BT_ChileExample.conf

Run an example illustrating the procedure of Multi-Band Filter Characteristic Function calculation:

mbf_plot  examples/MBF_ChileExample.conf
