A Python package for seismic surface wave tomography and receiver function analysis

surfpy

A Python package for surface wave tomography and receiver function analysis. This is an all-in-one package which includes several functions:

1. Data request for earthquake surface wave waveforms, teleseismic P wave (receiver function), continous waveforms (for ambient noise)
2. Ambient noise cross-correlation (two-station ambient noise interferometry)
3. Three-station ambient noise interferometry
4. Surface wave dispersion measurements (aftan)
5. Receiver function (rf) computation and harmonic stripping
6. Surface wave tomography (ray-based tomography and eikonal/Helmholtz tomography)
7. Bayesian Monte Carlo inversion(1. isotropic inversion using rf and Rayleigh wave; 2. VTI inversion using rf, Rayleigh waves and Love waves)
8. A least-square inversion for azimuthally anisotropic Vs model
