REM GMT EXAMPLE 22
REM
REM $Id$
REM
REM Purpose: Automatic map of last 7 days of world-wide seismicity
REM
REM GMT progs: gmtset, pscoast, psxy, pslegend
REM DOS calls: del, sed, awk, wget|curl
REM
echo GMT EXAMPLE 22
set ps=example_22.ps
gmt set FONT_ANNOT_PRIMARY 10p FONT_TITLE 18p FORMAT_GEO_MAP ddd:mm:ssF
REM Get the data (-q quietly) from USGS using the wget (comment out in case
REM your system does not have wget or curl)
REM wget http://neic.usgs.gov/neis/gis/bulletin.asc -q -O neic_quakes.txt
REM curl http://neic.usgs.gov/neis/gis/bulletin.asc -s > neic_quakes.txt
REM Count the number of events (to be used in title later. one less due to header)
REM n=`cat neic_quakes.txt | wc -l`
REM n=`expr $n - 1`
set n=77
REM Pull out the first and last timestamp to use in legend title
REM first=`sed -n 2p neic_quakes.txt | awk -F, '{printf "%s %s\n", $1, $2}'`
REM last=`sed -n '$p' neic_quakes.txt | awk -F, '{printf "%s %s\n", $1, $2}'`
set first=04/04/19 00:04:33
set last=04/04/25 11:11:33
REM Assign a string that contains the current user @ the current computer node.
REM Note that two @@ is needed to print a single @ in gmt pstext:
REM set me = "$user@@`hostname`"
set me=GMT guru @@ GMTbox
REM Create standard seismicity color table
gmt makecpt -Cred,green,blue -T0,100,300,10000 -N > neis.cpt
REM Start plotting. First lay down map, then plot quakes with size = magintude/50":
gmt pscoast -Rg -JK180/9i -B45g30 -B+t"World-wide earthquake activity" -Gbrown -Slightblue -Dc -A1000 -K -Y2.75i > %ps%
gmt psxy -R -J -O -K -Cneis.cpt -Sci -Wthin -h -i3,2,5,4+s0.02 neic_quakes.txt >> %ps%
REM Create legend input file for NEIS quake plot
echo H 16 1 %n% events during %first% to %last% > neis.legend
echo D 0 1p >> neis.legend
echo N 3 >> neis.legend
echo V 0 1p >> neis.legend
echo S 0.1i c 0.1i red 0.25p 0.2i Shallow depth (0-100 km) >> neis.legend
echo S 0.1i c 0.1i green 0.25p 0.2i Intermediate depth (100-300 km) >> neis.legend
echo S 0.1i c 0.1i blue 0.25p 0.2i Very deep (> 300 km) >> neis.legend
echo D 0 1p >> neis.legend
echo V 0 1p >> neis.legend
echo N 7 >> neis.legend
echo V 0 1p >> neis.legend
echo S 0.1i c 0.06i - 0.25p 0.3i M 3 >> neis.legend
echo S 0.1i c 0.08i - 0.25p 0.3i M 4 >> neis.legend
echo S 0.1i c 0.10i - 0.25p 0.3i M 5 >> neis.legend
echo S 0.1i c 0.12i - 0.25p 0.3i M 6 >> neis.legend
echo S 0.1i c 0.14i - 0.25p 0.3i M 7 >> neis.legend
echo S 0.1i c 0.16i - 0.25p 0.3i M 8 >> neis.legend
echo S 0.1i c 0.18i - 0.25p 0.3i M 9 >> neis.legend
echo D 0 1p >> neis.legend
echo V 0 1p >> neis.legend
echo N 1 >> neis.legend
REM Put together a reasonable legend text, and add logo and user's name:
echo P >> neis.legend
echo T USGS/NEIS most recent earthquakes for the last seven days. The data were >> neis.legend
echo T obtained automatically from the USGS Earthquake Hazards Program page at >> neis.legend
echo T @_http://neic/usgs.gov @_. Interested users may also receive email alerts >> neis.legend
echo T from the USGS. >> neis.legend
echo T This script can be called daily to update the latest information. >> neis.legend
echo G 0.4i >> neis.legend
echo I USGS.ras 1i RT >> neis.legend
echo G -0.3i >> neis.legend
echo L 12 6 LB %me% >> neis.legend
REM OK, now we can actually run gmt pslegend. We center the legend below the map.
REM Trial and error shows that 1.7i is a good legend height:
gmt pslegend -DjCB+o0/0.4i+w7i/1.7i+jTC -R -J -O -F+p+glightyellow neis.legend >> %ps%
REM Clean up after ourselves:
del neis.*
del .gmt*
del gmt.conf
