Introduction

This repository includes bash scripts that use Generic Mapping Tools (Wessel et al., 2013) to plot National Observatory of Athens NOA earthquake catalogue and historical earthquakes of Papazachos and Papazachou catalogue for the region of Greece. Also you can plot earthquake profiles ...

---

main scripts

1. plot_eq.sh : plot earthquakes
2. plot_eq_proj.sh : plot earthquakes and profiles
3. plot_hcmt.sh : plot moment tensors from historic earthquakes

helpful files

4. default-param : default parameters for paths, input files and region configuration
5. get_catalogue.sh : this script download earthquake NOA catalogue and fault database (Ganas et al., 2020)

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

For main scripts help function run:

  $> ./plot_eq.sh -h 
  ## (or)
  $> ./plot_eq_proj.sh -h

plot_eq.sh

MAIN OPTIONS

Usage : plot_eq.sh -r west east south north | -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
• updcat [:= update earthquake catalogue]
• topo [:= topography] use DEM topography
• faults [:= faults] plot NOA fault database
• histeq [:= historic eq ] plot historical eq via papazachos catalogue

EARTHQUAKE OPTIONS

• minmw [:= minimum magnitude] bug use only int
• maxmw [:= maximum magnitude] bug use only int
• starty [:= start year]
• stopy [:= stop year]

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:

$ ./plot_eq.sh -topo -faults -jpg -leg

---

plot_eq_proj.sh In these script added an optio to plot rofile of earthquakes

-eqproj [:=projection] plot projectio along profile use -eqproj lon lat Az Lmin Lmax Wmin Wmax depth

lon: start longitude of profile

lat: start latitude of profile

Az: Azimuth of profile

Lmin, Lmax: Profile Length start-stop

Wmin, Wmax: Profile width on the two sides of profile depth: depth of profile

Updates

• 21-1-2015: online version is available
• 03-8-2023: update to GMT v6.3.0, bug fixed
