SourceSpec documentation

Earthquake source parameters from P- or S-wave displacement spectra

Date

SourceSpec is a collection of command line tools to compute earthquake source parameters (seismic moment, corner frequency, radiated energy, source size, stress drop) 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 from source_spec output.
  • clipping_detection: Test the clipping detection algorithm.
  • plot_sourcepars: 1D or 2D plot of source parameters from a sqlite parameter file.
