SourceSpec is a collection of command line tools to compute earthquake source parameters (seismic moment, corner frequency, radiated energy, source size, static stress drop, apparent stress) from the inversion of P-wave and S-wave displacement spectra recorded at one or more seismic stations. SourceSpec also computes attenuation parameters (t-star, quality factor) and, as a bonus, local magnitude.
See :citeMadariaga2011 for a primer on earthquake source parameters and scaling laws.
Go to section theoretical_background:Theoretical Background
to get more information on how the code works.
SourceSpec is written in Python and requires a working Python environment to run (see installation:Installation
). However, since SourceSpec is based on command line, you don’t have to know how to code in Python to use it.
The SourceSpec package is made of several command line tools:
source_spec
: Compute earthquake source parameters from the inversion of P- or S-wave spectra.source_model
: Direct modelling of P- or S-wave spectra, based on user-defined earthquake source parameters.source_residuals
: Compute station residuals fromsource_spec
output.clipping_detection
: Test the clipping detection algorithm.plot_sourcepars
: 1D or 2D plot of source parameters from a sqlite parameter file.
