LinSlipInv

Linear multi time-window earthquake slip inversion with k^-2 smoothing

Suite of codes for linear slip inversions and resolution analysis.

Capabilities of the codes:

• Inversion of provided data for a given (possibly segmented) fault geometry
• Resolution analysis by means of synthetic tests with prescribed target rupture model or slip-rate pulse model
• Inversion in-depth analysis by means of spectral analysis of the forward matrix G
• Can take advantage of Intel MKL library and/or CULA (GPU) for faster performance
• Plotting the results

Possible data types for inversions:

• Seismic waveforms including processed HR-GPS
• Static GPS vectors

Implemented regularizations of the inversion:

• Truncated SVD
• Spatial k^-2 prior covariance function
• Positivity constraint on the slip rate functions

Included codes for evaluation of Green's functions:

• Axitra (full-wavefield in 1D layered media)
• Okada (static displacements in homogeneous halfspace)
