SourceSpec documentation¶
SourceSpec is a collection of command line programs (written in Python) to determine earthquake source parameters (seismic moment \(M_0\), corner frequency \(f_c\)) and the inelastic attenuation term (\(t^*\)), from the modeling 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 \(M_l\) is computed as well.
SourceSpec is composed of the following programs:
source_spec
: inverts the S-wave displacement spectra from station recordings of a single event.ssp_residuals
: computes station residuals fromsource_spec
output.source_model
: direct spectral modelling.
