Introduction

This repository includes bash scripts that use Generic Mapping Tools (Wessel et al., 2013) to plot teconic velocities and parameters of strain tensors

---

main scripts

1. gpsvelstr.sh : plots velocities and parameters of strain tensor

input files

1. default-param : default parameters for paths, input files and region configuration
2. input file for velocities (example test.vel)
3. input file for strain tensor (test.str)

Documentation

• Be sure that gmt is installed on your computer
• Configure file default-param.

If you'd like to use topography, you can download world DEM from here

INPUT FILES

• input file for velocitiew, use mm for velocities and uncertenties

code lat lon alt vN svN vE svE vU svU

• input file for straintensor parameters, K in μstrain and Az in degrees

code lat lon Kmax sKmax Kmin sKmin Az sAz E sE gtot sgtot

(do not use a seperator!)

MAIN SCRIPT: gpsvelstr.sh

MAIN OPTIONS

Usage : plot_eq.sh -r west east south north projscale frame| -topo | -o [output] | -jpg

• r [:= region] region to plot west east south north (default Greece) use: -r west east south north projscale frame
• mt [:= map title] title map default none use quotes
• topo [:= topography] use DEM topography
• faults [:= faults] plot NOA fault database

PLOT VELOCITIES

• vhor (input_file)[:= horizontal velocities]
• vver (input_file)[:= vertical velocities]
• vsc [:=velocity scale] change vElocity scale default (0.05)

PLOT STRAIN TENSOR PARAMETERS

• str (input file)[:= strains] Plot strain rates
• strsc [:=strain scale]

OTHER OPRTIONS

• o [:= output] name of output files
• l [:=labels] plot labels
• leg [:=legend] insert legends
• logo [:=logo] plot logo
• jpg : convert eps file to jpg
• h [:= help] help menu

Exit Status: 1 -> help message or error Exit Status: >= 0 -> sucesseful exit

Example:

$ ./gpsvelstr.sh -topo -faults -jpg -logo

plot velocity test file

$ ./gpsvelstr.sh  -jpg -topo -vhor test.vel -logo

plot strain rates from test file

$ ./gpsvelstr.sh -jpg -topo -str test.str -logo

Updates

• 20 Jan 2016: First release gpsvelstr script.
