seisloc

Seismic location using waveform migration based methods, including the Multichannel Coherency Migration method of Shi et al. (2018a, 2018b).

The codes can be freely used for NonCommercial activities, such as research and teaching.

Installation

To install the migrationloc programs, you need:

• A Fortran compiler
• An MPI installation for the MPI version of the code

Build the software by changing to the root directory of the repo, and typing:

make -C src

By default this will build the serial, OpenMP and MPI versions. Other make targets:

• serial : Only build the serial version
• mpi: Only build the MPI version
• openmp: Only build the OpenMP version

Compiler and compilation flags

By default, we use gfortran to compile the programs and mpif90 to link the MPI libraries.

To use the Intel compiler, set FC=ifort and MOD=module.
