ANCC

Some scripts for ambient noise tomography (support parallel computing and auto-correlation computation)

FDFK2D

Efficient two-dimensional teleseismic wavefield hybrid simulation method for receiver function analysis

PDS2SAC

A matlab script to convert the PDS2 file format to the SAC file format

Butterworth-Filter

Arbitrary-order Butterworth IIR Filter zero-phase forward and reverse digital IIR filtering.

seismic_cpml

SEISMIC_CPML is a set of sixteen open-source Fortran90 programs to solve the two-dimensional or three-dimensional isotropic or anisotropic elastic, viscoelastic or poroelastic wave equation using a finite-difference method with Convolutional or Auxiliary Perfectly Matched Layer (C-PML or ADE-PML) conditions, developed by Dimitri Komatitsch and Roland Martin from CNRS, France.

specfem2d

SPECFEM2D simulates forward and adjoint seismic wave propagation in two-dimensional acoustic, (an)elastic, poroelastic or coupled acoustic-(an)elastic-poroelastic media, with Convolution PML absorbing conditions.

specfem3d

SPECFEM3D_Cartesian simulates acoustic (fluid), elastic (solid), coupled acoustic/elastic, poroelastic or seismic wave propagation in any type of conforming mesh of hexahedra (structured or not). It can for instance model seismic waves propagating in sedimentary basins or any other regional geological model following earthquakes. It can also be used for non destructive testing or for ocean acoustics.
