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
