Paper online:

factor_irf

Just published in BSSA, we quantify variations in source parameter estimates at closely spaced stations. Accurate estimates of course parameters and their uncertainties are essential, particularly when the results are used in the comparisons among different studies over a range of earthquake magnitudes and locations.

map_time

We use an empirical Green’s function method to spectra estimated using the seismic coda to investigate earthquake source scaling. Our data span a magnitude range from Mw 3.0–Mw 7.1. We find that a constant scaled energy provides a reasonable fit to the data, with no dependence of scaled energy on seismic moment. Published in JGR. g can be generated from ambient noise. Figure above shows the IRF of the Factor Building in UCLA at two different frequency bands.

 

The GPLOT library is a plotting library that can be used to plot variables from inside any fortran program. This subroutine is not intended to replace other graphics packages, but to allow the user to look at arrays of data in the middle of fortran codes. It might be useful for debugging.

The program XYPLOT is also not intended to replace other programs, but to work as a user-friendly interactive program, in which plots of data files can be created from the command line. It is interactive in the sense that the user can input some parameters and the program can interpret the parameters given and create a plot of the desired data file.

How do I compile the library?
How about documentation?
Where do I download the source code?



How do I compile the Library?

The first thing you need to do, is of course download the source code (below) and have a F90 compiler (the free compiler G95 NOW does work) available.

Download, unzip and untar the file into a given directory, which we will call ~/gplot/

The latest version does not require you to change anything in the Makefile, unless you are not using GFORTRAN as your compiler. You can change the location of the output libraries and binaries by editing the make.inc file.

Compile simply tipying make.

The program XYPLOT can be found in ~/gplot/bin/ and should have been compiled already.

How about documentation?

Documentation is available here. gplot.pdf
