QSSP - Complete synthetic seismograms for a spherical earth

Notes: This is a modified version of the original code.

How to run this code?

1. compile

First, you should change your directory to $QSSPROOT/src, where $QSSPROOT is the root path of this code. Then, you can run make qssp to compile the code. After that, you can run make install, which will put the binary executable program (qssp) to a folder named $QSSPROOT/bin.

$ cd src
$ make qssp
$ make install

2. run a demo

In the $QSSPROOT folder, you can run the following command to get your first result.

$ mkdir GreenFunctions
$ ./bin/qssp ./demo/qssp2017-fig01.inp

What I have done?

add a Makefile to compile the code
modify qpmain.f to qpmain.f90 so we can pass the command-line arguments to the code

Code for calculating complete synthetic seismograms of a spherical earth using the normal mode theory.

Highlights

(1) all-in-one code for body waves, surface waves, free oscillations, tsunami for uniform ocean, infrasound waves for a standard atmosphere and static deformation
(2) generating Green’s function database or simulating complete seismograms for any given kinematic source model
(3) hybrid algorithm (numerical integration for low frequency / small harmonic degrees and analytical propagator algorithm for high frequency / large harmonic degrees)
(4) complex frequency technique for supressing the time-domain aliasing problem
(5) differential filter technique for suppressing numerical phases
