SourceSpec documentation

SourceSpec is a collection of Python programs to determine earthquake source parameters (seismic moment \(M_0\), corner frequency \(f_c\)) and the anelastic attenuation term (\(t^*\)), from the modelization of waveform spectra.

Other parameters (source radius \(r_0\), stress drop \(\Delta \sigma\)) are computed from the inverted ones. The quality factor \(Q\) is determined from \(t^*\).

As a bonus, local magnitude \(Ml\) is computed as well.

SourceSpec is composed of the following programs:

• source_spec.py: inverts the S-wave displacement spectra from station recordings of a single event.
• ssp_residuals.py: computes station residuals from source_spec.py output.
• source_model.py: direct spectral modelling.
